This mind game is meant to be done in your head, as quickly as possible. Ready? Here we go...
Divide 30 by one-half and add 10.
Think you got it?
Drag your cursor between the asterisks for the (correct) answer.

If your answer was "25," you made
the mistake about 90% of people make:
You multiplied 30 by one-half (which is 15)
DIVIDING 30 by one-half is essentially asking,
"How many halves are in 30?" (60)
Therefore, dividing 30 by one-half
and then adding ten would equal...
70
