Thanks for explaining everything Melody, I would have but my lazy bone acted up. Also Chemistry was calling my name.

Actually the answer is 42. Don't question it.

I'm guessing you put 1/3 into a calculator and saw this.

What the calculator is actually doing is rounding the number because 1/3 isn't very clean turning into a decimal, you'd need a sort of decimal of a decimal to get that number (Which don't exist, I think). So 1/3 is ABOUT .3333333333.... But 1/3 is the best way to go for an exact answer.

Any number divided by zero is undefined, the reasoning gets really messy... really really really messy. Even teachers can be dumbfounded by the explanation.

Number one is actually 9x^8 (You multiplied 3 by 2 instead of squaring it, silly mistakes can be fatal)

By looking at most of the others you got most correct, though silly mistakes in some, try going through the step by step progress with them again.

I don't exactly know what you are trying to do with those percent signs, you give no implication of a number being represented into percentages. If those were a typo of sorts, or... something then the answer above is the correct approximation.

(((7000000000/46)/.17)/5.52)= 162163163.94

Those percent signs made no sense. So I just did the math without them.
