3 \cdot (2) (- 1) - 5 \cdot 2 + 3 (- 1)

- 19

Solution steps

3 (2) (- 1) - 5 \cdot 2 + 3 (- 1)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

3 (2) (- 1) : - 6

3 (2) (- 1)

3 \cdot (2) = 6

3 (2)

Apply rule:

(a) = a

(2) = 2

= 3 \cdot 2

Multiply the numbers:

3 \cdot 2 = 6

= 6

= 6 (- 1)

Apply rule

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

6 (- 1) = - 6 \cdot 1 = - 6

= - 6

= - 6 - 5 \cdot 2 + 3 (- 1)

Multiply and divide (left to right)

5 \cdot 2 : 10

5 \cdot 2

5 \cdot 2 = 10

= 10

= - 6 - 10 + 3 (- 1)

Multiply and divide (left to right)

3 (- 1) : - 3

3 (- 1)

Apply rule

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

3 (- 1) = - 3 \cdot 1 = - 3

= - 3

= - 6 - 10 - 3

Add and subtract (left to right)

- 6 - 10 - 3 : - 19

- 6 - 10 - 3

- 6 - 10 = - 16

= - 16 - 3

- 16 - 3 = - 19

= - 19

= - 19
