Answer 1

In logic-oriented subjects like mathematics, the order of operations is a set of standard rules that reflect conventions about which process to perform first to evaluate a given numerical expression. With a basic summation that just has two numbers and one single operation, or sign, it's easy to calculate the result. Either you perform addition, subtraction, multiplication, or division.

But what if there are several numbers and different operations in an expression at the same time? Maybe you need to multiply and divide or divide and add. What do you do then?

For example, multiplication is given a higher precedence than addition, and it has been this way right from the time when modern algebraic notations were introduced. Thus, the expression 3 + 5 × 2 is interpreted to have the answer 3 + (5 × 2) = 13, not (3 + 5) × 2 = 16. When exponents were introduced in the 16th and 17th centuries, they were given precedence over both addition and multiplication and are used as a superscript to the right of their base. Thus, 2 + 52 = 27 and 2 × 52 = 50.

These conventions exist to eliminate any ambiguity while enabling notation to be as brief as possible. Where it is desired to override the precedence conventions, or just to emphasize them, parentheses (), , { } can indicate an alternate order or reinforce the default order to avoid confusion. For example, (2 + 3) × 4 = 20 emphasize addition to precede multiplication, and (3 + 5)² = 64 emphasize addition to precede exponentiation.
