This is a way to write numbers that are too big or small on a calculator. For example: 93,000,000 miles from the earth to the sun is 9.3 x 106 in scientific notation. The number is always written between 1 and 10 and the power on the 10 tells you how many places to move the decimal point. Positive exponents mean big numbers (greater than 10) and negative exponents indicate decimal numbers (less than 1).
