If you multiply integers the results is an integer. If you divide integers (with one exception) the result is a rational number which, in some cases, may be an integer. However, the exception is that division by 0 is not defined.
If you add, subtract or multiply rational numbers, the result will be a rational number. It will also be so if you divide by a non-zero rational number. But division by zero is not defined.

Because in alot of future jobs, you need to know how to add/subtract/divide/multiply negatves to positives and vice versa.
you divide and divide again then multiply then add then subtract then finally get the root
why is it important to know how to multiply
