Well I know how to multiply I just don't know how to estimate to get to my reasonable answer and some questions also use parentisis so does that mean I have another step to do.

"some questions also use parentisis"

**parentheses are used to indicate multiplication, as in 3(4) = 12**

**or in algebra as, for example, to explain the distributive property: a(b+c) = ab + ac.**

**298(31) can be ESTIMATED AS 300(30), which you can do mentally--approximately 9,000.**
