It's easy to convert from scientific to ordinary numbers. You just count the decimals! Move the decimal point to the right if it's a positive exponent and to the left if it's a negative exponent.

Two examples should make it clear.

3.14 x 10^3 = 3140. Why? Because I moved the decimal THREE TIMES to the right. Where did the zero come from? Because 3.14 is actually 3.140 but no one bothers with the zero since there's nothing there.

3.14 x 10^-3 = 0.00314. Why Because I moved the decimal THREE TIMES to the left. Once again, the zeroes are honorary place holders.
