Direction: A. What operation should be done first. (GEMDAS)

Answer:

1. 8 + 5 × 2 =18

2. 15 + 3² - 2 =22

3. 28 ÷ 7 + 3 × 2 =10

4. 14 - 8 + 5 =11

5. 18 × 10 ÷ 2 =90

6. 5 + 20 ÷ 4 - 3 =7

Solution:

#USING GEMDAS

#USING CALCULATOR

1)

=8 + 5 × 2

=8 + 10

=18

2)

=15 + 3² - 2

=15 + 9 - 2

=24 - 2

=22

3)

=28 ÷ 7 + 3 × 2

=4 + 3 × 2

=4 + 6

=10

4)

=14 - 8 + 5

=6 + 5

=11

5)

=18 × 10 ÷ 2

=180 ÷ 2

=90

6)

=5 + 20 ÷ 4 - 3

=5 + 5 - 3

=10 - 3

=7
