Use properties to find the sum or product 93 + (68+7)

The sum :93 + (68+7) = 168

Calculation operations include multiply, divide, add, substract, etc.

In mathematical operations we can use the order of operation / calculation according to the principle of PEMDAS

Multiplication and division or addition and subtraction are interchangeable/rank equally so the calculations/equation operations should be done from left to right

The sum or product 93 + (68 + 7)

From this problem, we can know that the calculated operation used is only an addition, so that the form of parentheses has no effect, but we still adjust to the guidelines in PEMDAS that we count the calculation operations in parentheses first

then :

6 squared divided by 2 (3) +4
