Riddle #40 (Three upvotes to the first correct answer posted in comments.)

Add two divide by 2 times 3?
Minus 1 minus 1 minus 1 times 3?
3?

The answer is correct. Good job. You must be using “new math.” 😀

I multiplied the numbers in the first two squares, and divided by the third number. Since the formula worked for both groups, 30 divide by 10 gave me three in the third group.
