In pre-algebra, we learned 2 forms. Standard and Scientific. The exponents' power were negative numbers, which made a big difference, because this time, we had to move the decimal to the right, and when the power is positive, then we move it to the left. I realized that the problems always used the number "10." I asked Mr. Dorman why, and he said that it was because in Science, they mostly focused on the number 10. It was a bit odd for me, but I'll accept it.
Raising positives to negatives can be confusing for a lot of people, especially for me. However, when you think about it, it's really easy.
