A way of expressing numbers that are too large or too small to be conveniently written in decimal form, using powers of ten.

Front

How do you multiply numbers in scientific notation?

Back

Multiply the coefficients and add the exponents. Example: (3.4 x 10^5)(1.2 x 10^-3) = (3.4 * 1.2) x 10^(5 + (-3)) = 4.08 x 10^2.

Front

What is the result of (3.5 x 10^2) + (2.1 x 10^3)?

Back

2.45 x 10^3.

Front

How do you divide numbers in scientific notation?

Back

Divide the coefficients and subtract the exponents. Example: (8 x 10^6) / (2 x 10^2) = (8/2) x 10^(6 - 2) = 4 x 10^4.
