One hundred times the quantity seven plus two

I have to write the expression and then figure it out

"seven" means ' 7 '

"two" means ' 2 '

"the quantity seven plus two" means ' (7 + 2) '

"one hundred times the quantity ... " means ' 100 (7 + 2) '

That's the expression.

One of the rules for handling these things is that you should always

take care of anything inside parentheses first. So do that.

(7 + 2) = 9

Now you can can write the expression like this: ' 100 (9) '.

That's just 900.
