57 - (24 plus 15) = 18
3(4 plus 7) equals 33
678 plus 935 equals 1622
100 - 10 + 3 = 93 You don't need any parentheses.
It's 2+(-34)=-10 So put the parentheses around the -34.
-2w+14+10w=348w=20w=2.5
With no parentheses, that equals 30.
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
The parentheses would be placed thus: 27 - (49 / 7 + 12) = 8
(1 + 8)*(8 + 2) = 90
2xy - 4x plus 8y - 16 equals x plus 4 in parentheses multiplied by 2y minus 4 in parentheses. So, the factors are ( x + 4) and ( 2y - 4) .
parentheses two times nine parentheses times negative eight minutes four parentheses four plus hundred plus eight
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.
