To clarify the order of operations in the math problem, you can use parentheses as follows: (3 times 42) plus (84 divide by 2) plus (2) equals 56.
2+(4+7)= 2+10= 12 so, the answer is twelve the correct way to say that arithmetic problem would be..... two plus the quantity four plus seven
-2w+14+10w=348w=20w=2.5
It's 2+(-34)=-10 So put the parentheses around the -34.
The parentheses would be placed thus: 27 - (49 / 7 + 12) = 8
