How do you multiply numbers in scientific notation?

Back

Multiply the coefficients and add the exponents: (a x 10^m)(b x 10^n) = (a*b) x 10^(m+n).

How do you add numbers in scientific notation?

Back

Make sure the exponents are the same, then add the coefficients: a x 10^n + b x 10^n = (a+b) x 10^n.
