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.

assuming that there are no parentheses around the (7-1) then it should be 10.7
Lets take the word problem and set it up into a mathematical problem. Twenty one plus four times twelve: 21 + 4(12). Always start with parentheses first. 21 + 48. Now do the addition. 21 + 48 = 69.
(-2)^3 equals -2 times -2 times -2 which equals -8
Parentheses and brackets are what are known as grouping symbol. They keep two or more quantities separate from the rest of the problem. For example, n-2 180. Without parentheses the problem is wrong. But add in parentheses and the problem looks like this (n-2) times 180.
parentheses two times nine parentheses times negative eight minutes four parentheses four plus hundred plus eight

That depends. (odd thing to say about a math problem, I know...)If there are parentheses anywhere then it changes. But, without any it's 5*-4^2=-80However, with parentheses it'll be positive ... 80

(15+80) x 90 = 95 x 90 = 8550

4*5+2*8=176
A "+" before parentheses means + 1 times everything inside, so +(a+b-c) means +a+b-c
