Multiplying in scientific notation with negative exponents

👉 Learn how to multiply numbers written in scientific notations. Scientific notation is a convenient way of writing very large or very small numbers. A number written in scientific notation is of the form a * 10^n where a is the first non-zero number between 1 and 10, (1 included) and n is the number of digits up to the decimal point.

To multiply two or more numbers written in scientific notation, we multiply the bases (the a parts) of the numbers and add the exponents (the n parts). We then adjust the decimal point to satisfy the condition for a in scientific notations (if need be). Remember to also adjust the value of n whenever the value of a is adjusted.
