Quandaries & Queries

Question from tyler, a student:

use all the numbers shown, any of the following four operations +,-,x, and division
and parentheses to make a total of 100. You may not change the order of the
numbers, or use them more than once.

1 2 3 4 5 6 7 8 9

Please help asap I can't figure this out. Thank you

Tyler,

Here's a hint: 1(10)(10) = 100. Try that.

PS: I'll add other ideas to this web page as they arrive. Check back in awhile and reload this page if my hint isn't enough for you to figure it out.
