49 \div (- 7) + 5 (- 3) (- 4)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

49 \div (- 7) : - 7

49 \div (- 7)

Apply rule

a \div (- b) = - a \div b

49 \div (- 7) = - 49 \div 7 = - 7

= - 7

= - 7 + 5 (- 3) (- 4)

Multiply and divide (left to right)

5 (- 3) (- 4) : - 60

5 (- 3) (- 4)

Apply rule

a \cdot (- b) = - a \cdot b

5 (- 3) = - 5 \cdot 3 = - 15

= - 15 (- 4)

Apply rule

a \cdot (- b) = - a \cdot b

15 (- 4) = - 15 \cdot 4 = - 60

= - 60

= - 7 - (- 60)

- (- a) = + a

- (- 60) = + 60

= - 7 + 60

- 7 + 60 = 53
