Best Answer - Chosen by Voters

5+5+5=15 (in money terms you get five dollars then another then another, now you have 15 dollars)

15-5=10 (someone takes away 5 dollars, now you have ten dollars)

10+5+5=20 (but they give you back ten dollars, now you have twenty dollars)

20-5=15 (now they take away five dollars, now you have fifteen dollars)

15+5=20 (but they give you five dollars back, now you have twenty dollars)

20X0=0 (think of the twenty dollars as how much money you have and you want to increase itif you multiplied your total of twenty dollars by two you would have two sets of twenty dollars, which equals forty dollars. if you multiply your twenty dollars by zero you would have zero sets of twenty dollars, hence 20X0=0)

Now for your question. The answer should be 15 because of the order of operations, which goes like this

1)Parenthesis
2)Exponents
3)Multiplication
4)Division
5)Additon
6)Subtraction

    The correct answer is 15. Here's why.

    5+5+5-5+5+5-5+5X0
    In an equation, you are supposed to multiply and divide first. So first you solve 5X0, which is 0. So now you are left with...
    5+5+5-5+5+5-5+0
    The next thing you do is add and subtract from left to right.
    So 5+5+5-5+5+5-5+0=15.

    Hope I helped! :)

    Since there are no brackets, the answer is 15, applying the rule that you multiply first, then add and subtract.
    The x 0 only applies to the last 5 making it equal 0
    It is 15 - 5 + 10 - 5 + 0 = 15

    The multiplication MUST be done first, so it is NOT zero.

    The answer is 15, since you must do the multiplication of 5x0 first then you do the rest.
