lol I need to know this too.
If they already know what they are why do you need to explain to them?
Every aspect of mathematics depends upon integers, and even if you don't do any mathematics, you count things with integers. If you even want to know how many guests you are having for dinner, you need to use integers.
why is it important to know how to multiply
you need to do the same thing as 2 digit integers is really easy

At least one of the integers is negative.
Fractions are integers when their denominator is 1 or when the numerator has the same value as the denominator.
why is it important to know how to multiply
-- Integers are very useful when you need to count things. -- If you are running short of decimal points and fraction bars, then integers are definitely the best numbers to use, since they don't need any of those.

Integers are very helpful when you are trying to count things, or when you want to tell somebody your age.
There is no need - it has already been done!
Because in alot of future jobs, you need to know how to add/subtract/divide/multiply negatves to positives and vice versa.
I'll exchange them for the numbers you want to know the GCF of.
