- 2 + (3) (4) - (- 5) 8

50

Solution steps

- 2 + (3) (4) - (- 5) \cdot 8

Follow the PEMDAS order of operations

Multiply and divide (left to right)

(3) (4) : 12

(3) (4)

(3) (4) = 3 \cdot 4

(3) (4)

Apply rule:

(a) = a

(3) = 3

= 3 (4)

Apply rule:

(a) = a

(4) = 4

= 3 \cdot 4

= 3 \cdot 4

Multiply the numbers:

3 \cdot 4 = 12

= 12

= - 2 + 12 - (- 5) \cdot 8

Multiply and divide (left to right)

(- 5) \cdot 8 : - 40

(- 5) \cdot 8

Apply rule

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

(- 5) \cdot 8 = - 5 \cdot 8 = - 40

= - 40

= - 2 + 12 - (- 40)

Add and subtract (left to right)

- 2 + 12 - (- 40) : 50

- 2 + 12 - (- 40)

- 2 + 12 = 10

= 10 - (- 40)

Apply rule

- (- a) = + a

- (- 40) = + 40

= 10 + 40

10 + 40 = 50

= 50

= 50

8 \cdot 3 \div 6 \cdot 10 \div 20

5 (0) - 7

12 (- 2)^{2} + 6 (- 2) - 6

15 \div 3 + 2^{3} \times 7

5 (0) + 2
