Evaluate.
1.12(3)(5+7)
2.12(15)(13+17)
3.12(10)(9.4+3.6)
4.12(2.1)(3.5+5.7)

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to
