Scientific notation on the MCAT is a common source of panic, because unlike simple long multiplication and division, it’s hard to fall back on pen-and-paper method.

This MCAT Math Without A Calculator tutorial video will show you how to tackle scientific notation if it shows up in the form of addition, subtraction, multiplication and division.

## Scientific Notation on the MCAT Video

In summary:

Addition of scientific notation: Ensure you have the same exponent power, add the coefficients

Subtraction of scientific notation: Ensure you have the same exponent power, subtract the coefficients

Multiplication of scientific notation: Multiply the coefficients and add the exponents

Leah on 2:00 minutes, are you dividing by 10 to move the decimal to the left to get -4?? and then you justified it for the other side as well dividing by 10 to get the decimal to also move to the left and get 50 right? I got confused there…..
