Objective: I know how to perform mixed operations with brackets or parenthesis, exponents, multiplication, division, addition, and subtraction.
If the calculations involve a combination of brackets or parenthesis, exponents, multiplication, division, addition, and subtraction then you need to follow the BEDMAS rules:
Step 1: First, perform the operations within the brackets or parenthesis
Step 2: Second, evaluate the exponents.
Step 3: Third, perform multiplication and division from left to right.
Step 4: Fourth, perform addition and subtraction from left to right.
The following diagram shows the BEDMAS rules for order of operations.
Calculate 23 – 3 × (8 – 6)
23 – 3 × (8 – 6) (perform within brackets or parenthesis)
= 23 – 3 × 2 (evaluate the exponent)
= 8 – 3 × 2 (perform multiplication)
= 8 – 6 (perform subtraction)
