GEMDAS means Groupings, Exponent, Multiplication, Division, Addition, Subtraction

ps. Nilagyan ko ng GEMDAS yung number 1 and number 2 para maintindihan nyo.

1. 46 - 6² + 36     exponent

  46 - 36 + 36     addition

  46 - 72              subtraction

 -26

2. (4 × 5²) + (3 × 10)   grouping

  (4 × 25) + 30           exponent

  (4 × 25) + 30           multiplication

  100 + 30                  addition

 130

3. 7² ÷ 7 + 5 × (9 - 5)

  7² ÷ 7 + 5 × 4

  49 ÷ 7 + 5 × 4

  49 ÷ 7 + 20

  7 + 20

  27

4. 84 ÷ 3 × 4 + 3³

  84 ÷ 3 × 4 + 27

  84 ÷ 12 + 27

  84 ÷ 12 + 27

  7 + 9

  34

5. 4³ + (8 - 4) ÷ 2 × 5

   4³ + 4 ÷ 2 × 5

   64 + 4 ÷ 2 × 5

   64 + 4 ÷ 10

   64 + 2/5

   322/5 or 64.4
