C= two step equations require all number to be whole number in order to solve.

Here is an example that disproves that:
 .5x + 8= 18
  <u>      -8     -8</u>
<u>.5</u>x = <u>10
</u>.5       .5

x = 20  (.5 is certainly not a whole number but I solved it anyway)

1 x 1 x 99 x 100 hat is the awnser
sashaice [31]
The answer to this equation is 9,900. Why? Well, we can solve this equation in left-to-right format, seeing that there are no brackets, exponents, or parenthesis:

Step One: 1 x 1 = 1. Anything multiplied by one is the same number that was started with.

Step Two: 1 x 99 = 99. Again, anything multiplied by one is the same number that we started with, which in this case was 99.

Step Three: 99 x 100 = 9,900. Because 100 is a power of ten, we could easily find the solution by shifting the digits two places to the left to increase their value. However, if you would like to do it the long way, you could simply write out 100 x 99 and solve it.

Your final answer: 1 x 1 x 99 x 100 = 9,900.
