<span>When multiplying numbers written in scientific notation you can take the numbers without the 10^exponent part and multiply them and then add the exponents of the base 10 powers. For example (A*10^B) * (C*10^D) is the same as (A*C)*10^(B+D).
For dividing it works the same way, only instead of adding the exponent you subtract them. For example (A*10^B) / (C*10^D) is the same as (A/C)*10^(B-D).</span>
