Answer :

I believe there is no way to solve this question. If you add one more ten or take away one ten it would work:

100 / (10 / (10 / 10)) = 10

But you cannot do this with the current equation.

100/10/(10/10)

100 divided by 10 equals 10.

10 divided by 10 equals 1.

100 divided by 10 divided by 1 equals 10.

100/10/(10/10)

=10\1

=10
