Order of Math Operations

We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication, and Division (from left to right), Addition, and Subtraction (from left to right).

We are given the expression

9 ÷ 3 + 1 = 4

If we follow the natural order of operations given in the rule above, then the sequence is: Division and then sum, thus:

9 ÷ 3 + 1 = 3 + 1 = 4

We can see the result is correct.

If we did it the other way, we had to operate the parentheses first:

9 ÷ (3 + 1) = 9 ÷ 4 = 2.25

Thus, the first choice is correct.
