ORDER OF OPERATIONS

3 + 4 x 2 Evaluate the following arithmetic expression: x 2 Each student interpreted the problem differently, resulting in two different answers.

one correct answer, When performing arithmetic operations there can be only one correct answer, so we need some rules to avoid confusion. First solve any calculations inside parentheses. solve all multiplications and divisions, working from left to right Last, solve all additions and subtractions, working from left to right.

Let's look at some examples of solving arithmetic expressions using these rules.

Evaluate ÷ (8 - 3) x using the order of operations Evaluate 150 ÷ (6 + 3 x 8) - 5 using the order of operations.
