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.

**Example:**

Calculate 2^{3} – 3 × (8 – 6)

**Solution:**

2^{3} – 3 × (8 – 6) *(perform within brackets or parenthesis)*

= 2^{3} – 3 × 2 *(evaluate the exponent)*

= 8 – 3 × 2 *(perform multiplication)*

= 8 – 6 *(perform subtraction)*

= 2
