Changing a Number from Standard Form to Scientific Notation

In order to change a number from standard form to scientific notation, you must first rewrite the number so it is between 1 and 10 by moving the decimal either to the left or right. For example, 32,581 would be changed to 3.2581. Then multiply the number by 10 raise to the power of how many places you moved the decimal. In the previous example, we moved the decimal over four spaces, which means 3.2581 should be multiplied by 104. Written out, it looks like this:

32,581 = 3.2581×104.
