Standard Example

Calculate: 3 + 4 × 2² - (6 - 2)

Step 1 Brackets first

= 3 + 4 × 2² - 4

(6 - 2) = 4

Step 2 Indices (powers)

= 3 + 4 × 4 - 4

2² = 2 × 2 = 4

Step 3 Multiplication

= 3 + 16 - 4

4 × 4 = 16

Step 4 Addition and Subtraction (left to right)

= 19 - 4 = 15

3 + 16 = 19, then 19 - 4 = 15

Answer: 15

Quick Recall Flashcards

Calculate: 10 - 2²
**Step 1:** Indices first (BIDMAS) 2² = 4 **Step 2:** Then subtraction 10 - 4 = **6** *(Not 10 - 2 = 8, then 8² = 64)*
Calculate: 2 + 3 × 4
**Step 1:** Multiplication first (BIDMAS) 3 × 4 = 12 **Step 2:** Then addition 2 + 12 = **14** *(Not 2 + 3 = 5, then 5 × 4 = 20)*
