    Using PEMDAS the answer is 4…..here is how: 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 – 1 + 1 + 1 + 1 + 1 + 1 + 1 x 0 =

    You would first do 1 x 0= and get 0.

    Then you add the 1’s till the minus sign (1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1) which is equal to 10.

    Then you add what ever is left after the minus sign and get 6 (1 + 1 + 1 + 1 + 1 + 1).

    Then you add the 0 to the 6 and you get 6.

    Then you subtract 10 – 6=4……simple math !!!!!!

    BTW, I used a regular calculator and got 14. However, if you would use a scientific calculator, then I believe the answer will be 4.

    gotbeer: It doesn’t work like that. With no parentheses, you don’t subtract 6, you subtract 1. In PEDMAS you do the division and multiplication from left to right, then the addition and subtraction from left to right. You don’t put in parentheses that weren’t in the original problem.

    Now that we’ve had over 50 comments discussing a fifth-grade math question entailing addition, subtraction and multiplication, perhaps we can move up a notch unto division:

    Can we extend this for another 50 responses, debating this highly complex equation?

    There is a thing called precedence of operations in algebra. In the lack of any type of parenthesis, the order is division, mult, subtraction and addition. First, you mult. Then all the adding stuff. Should come out to 14, on a good day. Is this an advanced Beis Yaakov arithmetic test, or what?

    Are you sure you didn’t find the answer to

    ? 1/(?(1+4t^2)) dt

    Or

    ? dt/(1+4t^2)

    instead of

    ? ?(1+4t^2) dt

    ? : ) I couldn’t find that particular one on Google, but there are (lengthier) ways of solving it, and programs that calculate anti-derivatives for you.

    1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 – 1 + 1 + 1 + 1 x 0 = ?

    Using PEMDAS, I started with 1 x 0. Automatically, that takes away that 1.

    Then, all I did was just follow the line. Since I took the last 1 away, the problem looks like this:

    1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 – 1 + 1 + 1 = ?

    I added 14 1’s and subtracted 1 as shown.

    My answer is 13.

    My answer is 13.

    You changed the question, so you got a different answer. The answer to the OP’s question is still 14.

    If the question was “1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 – 1 + 1 + 1 + 1 x 0 = ?”, the answer would be 12.

    x = y.

    Then x^2 = xy.

    Subtract the same thing from both sides:

    x^2 – y^2 = xy – y^2.

    Dividing by (x-y), obtain

    x + y = y.

    Since x = y, we see that

    2 y = y.

    Thus 2 = 1, since we started with y nonzero.

    Subtracting 1 from both sides,

    1 = 0.

    The correct answer is 4. 0x1= 0. Then there are 10 ones on the left of the subtraction sign. And 6 on the right side. Finally 10 minus 6 equals 4. Basic order of operations, and looking closely at the equation. You’re very welcome.

    Anything that is multiplied by zero, no matter how many digits it has = zero.

    Unless there is a parentheses in there somewhere at the very end, in which case the answer would actually be a real number.

    gotbeer and notoriouspre – BODMAS (or, as you seem to call it in America, PEDMAS) is a list of 4 operations, not 6: 1. Brackets, 2. Other (indices, surds etc), 3. Division AND Multiplication 4. Addition AND Subtraction. When faced with a problem like the one above, do ALL the multiplications and divisions first, from left to right (unless the division is expressed as a fraction in which case deal with the numerator and denominator separately), then ALL of the additions and subtractions from left to right, not all the additions first then all subtractions. So in this case, first do the 1×0 as you said but then you do not add all the 1’s to the left of the subtraction sign and subtract all the 1’s to the right of it from them but rather you add all the 1’s to the left then subtract the 1 immediately to the right of the subtraction sign and then carry on adding all the 1’s.

    oomis – See above. Always do multiplications and divisions BEFORE additions and subtractions. So the only thing being multiplied by 0 here is the very last 1. You can add and subtract all the rest afterwards. Incidentally, 0 is also a real number.

    PulsingFlower- I see it as ignorance. The concept isn’t difficult. The issue is that many people have never come across the concept in a way that they remember. This shows a lack of schooling (or an awful memory, which perhaps might be pitiful, but it doesn’t seem that you were thinking along those lines), and lack of any real life experiences that require simple math rules. Many people have no need for such knowledge and live complete lives without it. I don’t see inherent value in knowing simple math rules, thus I have no pity for those who were never exposed to them.

    #1125408

    I made the same mistake. my math woes are well documented on this site ( see one of the Lakewood matzav threads where boruch Schwartz absolutely schooled me on some simple math thingy). when I see a math example, my attention gets divided, my misery gets added, and my pleasure gets subtracted. I used to think algorithims are statements attributed to a former vice president and global warming alarmist. its not ignorance, just nerves I get nervous and cant think straight

    OK seriously…

    Yes anything times zero is zero. And if you have pq=0 then you know either p is 0 or q is 0 or both.

    Another way to think about multiplication is that you are making combinations. If I had 3 colors and 4 shapes then I have 3×4 = 12 combinations of colored shapes.

    But if I had 5 shapes and no colors I would have zero combinations of ‘colored shapes’ since…there are no colors.

    And that’s the nice thing about multiplication, because you can take say velocity and time, multiply them together, cancel the units and get the distance.

    It depends on how you perceive the last two numbers listed. ANYTHING you add or subtract and then multiply by 0, will always be 0. Unless the last two numbers were bracketed together as [1+0], which would actually be 1, the 0 becomes the multiplier, thus ending in a solution of…0 in this problem.

    oomis sorry you are wrong. We have to follow the rules. You said

    “ANYTHING you add or subtract and then multiply”

    No we multiply first and then add!

    So 1 + 1 X 0 = 1 because we first evaluated the multiplication of 1 X 0 = 0

    So we have 1 + 0 and that’s 1

    Oomis, the beauty of math is there is no such thing as “depends how you percieve it” there are strict rules as several posters have explained. following PEMDAS the answer is 14 ANY other response is simply wrong.
