**Ms. Sue**, Sunday, June 5, 2011 at 4:07pmIt's impossible to solve this problem without the use of parentheses.

For instance, 2 times 2 plus 7?

(2 * 2) + 7 = 11

or

2 * (2 + 7) = 18

**Rachel**, Sunday, June 5, 2011 at 4:11pm2•2=4, 7•3=21, 4•3=12, 3•2=6 ... 4+21=25, 25+12= 37, 37+3= 40, 40+4=44, 44+6= 50... I'm no math genius but I hope that I helped, the answer is 50.

**MathMate**, Sunday, June 5, 2011 at 5:14pmThis looks to me a mathematical expression, and not a puzzle.

It should come straight from the calculator as 50.

2*2+7*3+4*3+3+4+3*2

=4+21+12+3+4+6

=50

Ruby took the "*" sign as an exponential operator. I took it as multiplication, and we need to respect the order of operations, namely multiplication and division before addition and subtraction.
