Adding and Subtracting Scientific Notation

Front

What is scientific notation?

Back

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 add numbers in scientific notation with different exponents?

Back

Convert them to the same exponent, then add the coefficients.
