Well honey, if you want to find a number that will give you 7 after all those shenanigans, just work backwards. Start with 7, add 2 to get 9, multiply by 4 to get 36, then divide by 3 to get 12, and finally subtract 5 to get your magic number 7. Voilà!
PEMDAS: parenthesis exponents multiply divide add subtract prentices
The order of operations can be remembered by the using PEMDAS. Parenthesis, exponents, multiply or divide (whichever comes first left to right) , add or subtract (whichever comes first left to right).
Start with the equation equaling 7; 3/4(X + 5) - 2 = 7 X + 5 = 4/3(7 + 2) = 4/3 x 9 = 12 X = 12 - 5 = 7
Addition (+) is the opposite of subtract (-).
If you are speaking of Algebra, the order of operations is know as PEMDAS P=PARENTHESE E=EXPONETS M=MULTIPLY D=DIVIDE A=ADD S=SUBTRACT In order to solve an equation you must use this operation, if not you will not get the answer.

The order of operations is: P (parentheses) E (Exponents) M (Multiply) D (Divide) A (Add) S (Subtract)
0 Order of operations dictates you multiply before you subtract.
The four basic operations are … >> Add >> Subtract >> Multiply >> Divide Everything else is built on those four operations.
