A lot of people are having trouble with this math problem that requires some basic algebra

This is interesting and also shows you how basic skills need to be retained for life, and exercised somewhat. The fact we went from 80 percent to 60 shows our glorious education system is not working.

    The problem has nothing at all to do with algebra. It is about simple math, fractions and about operator precedence in math statements containing infix notation. No algebra present or needed. Precedence rules are a pain. In software I prefer prefix or postfix. In prefix notation using lisp (+ (- 9 (* 3 1/3) 1). One the proper grouping of operators in understood the rest is easy.

    I see your point, and I think it ties into what a lot of people see as issues in varying forms, some see the politics, some see the money side, some see the overall impact and impossibility of continuing on this way. It is the frustration of those that have no choice in the matter, from their perspective. The fact the masters gave us 2 idiots, and that the rest of them are not a winner either, leaves them frustrated and facing 4 more years of decay. If there was just some basic honor codes followed, a lot of this would not happen. People like we see flooding the Obamanations gang have no concern except for themselves and their cronies, and the same on the Repub side, leaving the 95 not in either camp to just shut up and dies.

    The problem is they are dealing with it as a control issue and not a budgeting issue and find themselves deeper and deeper into a situation which cannot be maintained. At some point a major crash is inevitable. The reality of their fiction will not serve and will not answer. Their problem will gave be have become too big not to fail.

    When inflation, devaluation and debt repudiation became so huge the French issued new money. One new franc was equal to ten old francs. Which still left the problem of the elderly and those on unfunded retirement programs. Waking up to find your $5,000 a month reitement income had become $500.00 but the loaf of bread at $2.00 new money wa still $20 old money. was a hard choice and it did bring on fixed prices on staple items. If $5.00 was chosen as the price for a loaf of bread it was still five times greater or put another way the buying power was now 20% of that planned for. So far ours has taken around a one third not an eighty percent cut with no COLA adjustment.

    That's just the first go round. At some point those debt notes will come due from the last bail out. The old folks still can't work even assuming there were jobs. Military get job preference for many situations. That 30% I mentioned in the initial presentation of the end user consumption tax will be forced up at least to 50%. When it reaches the same amount as the present system - why bother changing? At some point the debt will be so huge there will cease to be a point to even pretend to pay it off. other than by stealing from not only Grandpa and Grandma's retirement account but for the worker bees of ALL income levels as welll through inflation, devaluation and debt repudiation. That last means when they cause a decrease in buyiut they do not repay and do it openlyng power they don't count it in COLA. They steal but do not repay the theft knowing you will still vote for them.

    Therefore I propose anyone who votes for Trump or Hillary the two remaining socialists be dubbed the Dumb Ass Party the perfect name for the combination of Republicans and Democrats.

    Margaret Thatcher first said, "Socialism works until you run out of Other Peoplel's Money."

    Nancy Pelosi is thought to have said but some attribute this to Clinton and Reid - "Then you take the rest of what they have as long as we pay the Protective Echelon first. Homeland "Security is not for everyone."

    The problem the politicos have with a consumption tax is that everyone says their stuff should be exempt (it's a necessity) and it varies with economic cycles. So politicos need to have a variety of ways to fleece us....

    Back to the half chicken can't lay an egg issue that's the fallacy of rounding up. instead of down. 50 of 100 is the lower half and not the upper half. Rounding up is therefore always wrong. 1-50 becomes zero and 51 to 100 becomes 100 in correct rounding. There fore one half chicken will not only not lay an egg neither will it's smiley face farmer owner/operater.

    Can you run a truck on nine tires instead of 18?

    If the vehicle is traveling at 50mph in relationship to the road how fast is the tire moving?

    There is no adding in. All taxes are done away with and one end user consumption tax at final point of sale is used to replace the rest. Additional taxes VAT and other tax on taxes etc. are forbidden.

    Therefore there is no income tax at any percentage including Flat Tax.

    The major difference between a small reduction in gross tax paid is in the area of control.

    Income tax is confiscatory or as I put it fascist in nature Government decides and it varies only as a function of your salary as it changes.

    End User consumption tax citizen end consumer decides what and when to buy or not to buy and in what price range.

    Government is not allowed to go into deficit except for declared wars or natural katrina style disasters. Those two costs are automatically the top of the list for next years budget.

    Entitlements are phased out and the nearest thing go an income tax is phased in. 5% minimum for retirement NOT in a government controlled but in a controlled account. So no IOUs.

    One additional would be medical care account at 5% minimum

    The only deduction is the Right To Life the amount needed to survive. Government has zero right to take that which is needed to survive.

    That's it.

    Government takes what comes in through auto matic cash register transfers end of day, week month whatever.

    That's what they get to spend. If they want more money they have to improve the market place not put more chains on it.

    BUTthey retain the basic duties of military and police, judicial, and setting standards The unit that sets standards recommends congress approves, judicial handles any court issues, LEA enforces in separate branches.

    Nets out at an immediate 30% reduction in government employees. Watchi me cry ha ha

    Half chickens lay half eggs, which are sometimes used in quantity. Look at the typical recipe that an average family with 2.3 children would use for the filling of a key lime pie. Four half eggs (just the yolks.)

    Thanks Steven, I was aware of it being Asimov, I was tying back to the "good engineer" point, but thanks for the lesson, I just would not have had the patience to work it through, I was busy trying to re-engineer my grand daughters Ninentendo 3DXL whose screen broke. I bought a screen and was not daunted by the incredily small connectors and bits and pieces, but was finally defeated when it came to getting a size F tiny ribbon cable through a round hole, and found there is no one who has mastered it, and will confess to such knowledge. It is easy to see they use a slot in the factory, which is then masked when it is assembled and you cannot remove the pin. For the sake of expediency, I threw 250.00 at the problem and bought her a replacement, but kept all the pieces for future study. There must be a way to do it, just have to find it. Math doesn't help much in those scenarios...which is 90% of the engineering problems I normally deal with...

    I have loved every book he ever wrote, and have hardcopy as well as audio. I cannot go without rerunning Starship Troopers and The Moon is a Harsh Mistress, just for the object lessons he offered. I was so depressed when they made the movie and essentially trashed it. Made me realize that studios have no interest in preserving art, but manipulate it for their own ends.

    The great science and science fiction writer, Isaac Asimov engineered the egg, chickens, and days.

    Set it up and include the units, which multiply or divide just like everything else (most non-engineers don’t realize this—in case non-nerds are looking), the answer is:
    9 chickens × 9 days × (1½ eggs/1½ chickens)/1½ days

    Rewriting, bunching the numbers and bunching unit pairs together:
    9 × 9 × (1½/1½)/1½ × eggs × chickens/chickens × days/days
    Consider that a/a = 1 for all values of a, including units (non-zero, finite values).
    1½/1½ = 1, chickens/chickens = 1, and days/days =1

    So far:
    9 × 9 × (1)/1½ × eggs × 1 × 1
    Multiplying by 1 doesn’t change a value, and rewriting 1½ as an improper fraction of 3/2:
    9 × 9 × 1/(3/2) × eggs

    Consider that to divide by a fraction, you multiply by its reciprocal. Or 1/(a/b) = b/a
    We’re down to 9 × 2/3 of 9 in units of eggs. 2/3 of 9 is 6.
    9×6 eggs = 54 eggs.
    QED (Quite Easily Derived). Maybe its Quod Erat Demonstrandum.

    I just got that one. The local library was making space and discarded it. Also, got JOB: A Comedy of Justice which I read about 20 years ago.

    I can see your meaning here. There is no formative system in a lot of "systems", just the social movements, as in markets. Look at the Stock Market, it is a system, but responds to many different stimuli, and the controls seem mainly instigated by outside agencies to influence the amount of variation.

    It may be that the law of causation deals more with physical reality than with intention of a mind. In the short time period that a mind is able to initiate a body's action to shoot a 50 cal slug through a persons head would be the cause of the death of the person who was shot. It could even be said that such a shot will be the cause of a death. The properties of the shot are important to how one views it. Does one say the person who made the shot is the cause of the death? That is what happens in a court of law with various possibilities, the shot was by intent or by carelessness or by poor aim or by self defense or whether someone got your gun and took a shot of some type, etc. In today's world even the last is being considered as though the owner of the gun caused the death.
    Maybe it is the difference between actual instance of some action which would be considered to be the cause in that instance as to a general situation where something occurs and something not involved in the action is considered to be the cause of the action, something like the cause of cancer is water since water is involved in every person who gets cancer but really is correlation.
    To keep from going crazy, perhaps it is best in most cases to just say consistency is a necessary and sufficient condition for existence. If it exists it is consistent and if it is consistent it exists. A little difficult there for mental patterns though they too do not exist unless consistent whether chemical or some other process and must be non-contradictory.

    Hmm..I am not sure where you wanted to go with this, I was just saying by your numbers it looked like you were adding in sales tax. Not fond of any tax in general but it seemed you were aiming at a flat tax in your above?

    I agree with you points, I would say that in the thought arena, you have the issue of intent, which in and of itself would not be causative but can lead to an action, and the emotional aspect would have to dove tail in. So how does that work, with someone like Hillary? When it comes to causative effects and people, I see having a hard time, as you never have good data except in large groups, and even then it s more than likely skewed by some other factor. The climate thing is exactly correct, and is one reason the whole climate change thing is a farce to assume it is man caused,

    When I think of systems, there are inputs, outputs, and some transfer function that describes the outputs as a function of inputs and time. There are specs that describe how we want it to respond to changes in input. This whole area is often called "controls theory" in engineering.

    When they call the hoards of people wanting to buy something and sell something, aka a market, a "system" it sounds like the person talking wants to control it. It implies there are a set of specs that someone else wrote defining desires outcomes, rather than just whatever people feel willing to part with their money for.

    This is a pet peeve for me. Thanks for listening to my rant.
