10-2(-3)+5(0)-(-7)(-4)

10 - 2 (- 3) + 5 (0) - (- 7) (- 4)

- 12

Solution steps

10 - 2 (- 3) + 5 (0) - (- 7) (- 4)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

2 (- 3) : - 6

2 (- 3)

Apply rule

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

2 (- 3) = - 2 \cdot 3 = - 6

= - 6

= 10 - (- 6) + 5 (0) - (- 7) (- 4)

Multiply and divide (left to right)

5 (0) : 0

5 (0)

Apply rule:

(a) = a

(0) = 0

= 5 \cdot 0

Apply rule:

a \cdot 0 = 0

= 0

= 10 - (- 6) + 0 - (- 7) (- 4)

Multiply and divide (left to right)

(- 7) (- 4) : 28

(- 7) (- 4)

Apply rule

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

(- 7) (- 4) = 7 \cdot 4 = 28

= 28

= 10 - (- 6) + 0 - 28

Add and subtract (left to right)

10 - (- 6) + 0 - 28 : - 12

10 - (- 6) + 0 - 28

Apply rule

- (- a) = + a

- (- 6) = + 6

= 10 + 6 + 0 - 28

10 + 6 = 16

= 16 + 0 - 28

16 + 0 = 16

= 16 - 28

16 - 28 = - 12

= - 12

= - 12

(40 \times 2) - (6 \times 11)

- 3 - 1 + (- 1 - 2) - (- 2 - (- 3) + 1) - (- 2)

\frac{4 - 4}{4 ^{2} - 16}

750 \div 100 \times 600

\frac{[ ( - 6 + 4 ) - 6 - ( - 4 - 10 ) ]}{- 2}
