Find the value of

1. 36 ÷ 6 + 3

Solution:

Given 36 ÷ 6 + 3

According to BODMAS rule we have operate division first then we have to do addition

Therefore 36 ÷ 6 + 3 = 6 + 3 = 9

2. 24 + 15 ÷ 3

Solution:

Given 24 + 15 ÷ 3

According to BODMAS rule we have operate division first then we have to do addition

Therefore 24 + 15 ÷ 3 = 24 + 5 = 29

3. 120 – 20 ÷ 4

Solution:

Given 120 – 20 ÷ 4

According to BODMAS rule we have operate division first then we have to do multiplication

Therefore 120 – 20 ÷ 4 = 120 – 5 = 115

4. 32 – (3 × 5) + 4

Solution:

Given 32 – (3 × 5) + 4

According to BODMAS rule we have operate in brackets first then we have move to addition and subtraction.

Therefore 32 – (3 × 5) + 4 = 32 – 15 + 4

= 32 – 11 = 21

5. 3 – (5 – 6 ÷ 3)

Solution:

Given 3 – (5 – 6 ÷ 3)

According to BODMAS rule we have operate in brackets first then we have move to subtraction.

Therefore 3 – (5 – 6 ÷ 3) = 3 – (5 – 2)

= 3 –3 = 0

6. 21 – 12 ÷ 3 × 2

Solution:

Given 21 – 12 ÷ 3 × 2

According to BODMAS rule we have perform division first then multiplication and addition.

Therefore, 21 – 12 ÷ 3 × 2 = 21 – 4 × 2

= 21 – 8 = 13

7. 16 + 8 ÷ 4 – 2 × 3

Solution:

Given 16 + 8 ÷ 4 – 2 × 3

According to BODMAS rule we have perform division first then followed by multiplication, addition and subtraction.

Therefore, 16 + 8 ÷ 4 – 2 × 3 = 16 + 2 – 2 × 3

= 16 + 2 – 6

= 18 -6

= 12

8. 28 – 5 × 6 + 2

Solution:

Given 28 – 5 × 6 + 2

According to BODMAS rule we have perform multiplication first then followed by addition and subtraction.

Therefore, 28 – 5 × 6 + 2 = 28 – 30 +2

= 28 – 28 = 0

9. (-20) × (-1) + (-28) ÷ 7

Solution:

Given (-20) × (-1) + (-28) ÷ 7

According to BODMAS rule we have perform division first then followed by multiplication, addition and subtraction.

Therefore, (-20) × (-1) + (-28) ÷ 7 = (-20) × (-1) – 6

= 20 – 6 = 16

10. (-2) + (-8) ÷ (-4)

Solution:

Given (-2) + (-8) ÷ (-4)

According to BODMAS rule we have perform division first then followed by addition and subtraction.

Therefore, (-2) + (-8) ÷ (-4) = (-2) + 2

=0

11. (-15) + 4 ÷ (5 – 3)

Solution:

Given (-15) + 4 ÷ (5 – 3)

According to BODMAS rule we have perform division first then followed by addition and subtraction.

Therefore, (-15) + 4 ÷ (5 – 3) = (-15) + 4 ÷ 2

= -15 + 2

= -13

12. (-40) × (-1) + (-28) ÷ 7

Solution:

Given (-40) × (-1) + (-28) ÷ 7

According to BODMAS rule we have perform division first then followed by multiplication, addition and subtraction.

(-40) × (-1) + (-28) ÷ 7 = (-40) × (-1) – 4

= 40 – 4

= 36

13. (-3) + (-8) ÷ (-4) -2 × (-2)

Solution:

Given (-3) + (-8) ÷ (-4) -2 × (-2)

According to BODMAS rule we have perform division first then followed by multiplication, addition and subtraction.

(-3) + (-8) ÷ (-4) -2 × (-2) = -3 + 2 -2 × (-2)

= -3 + 2 + 4

= 6 – 3

=3

14. (-3) × (-4) ÷ (-2) + (-1)

Solution:

Given (-3) × (-4) ÷ (-2) + (-1)

According to BODMAS rule we have perform division first then followed by multiplication, addition and subtraction.

(-3) × (-4) ÷ (-2) + (-1) = -3 × 2 -1

= – 6 – 1

= -1
