12-8\div (-4)+5(-3)(5)(-4)

12 - 8 \div (- 4) + 5 (- 3) (5) (- 4)

314

Solution steps

12 - 8 \div (- 4) + 5 (- 3) (5) (- 4)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

8 \div (- 4) : - 2

8 \div (- 4)

Apply rule

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

8 \div (- 4) = - 8 \div 4 = - 2

= - 2

= 12 - (- 2) + 5 (- 3) (5) (- 4)

Multiply and divide (left to right)

5 (- 3) (5) (- 4) : - 300

5 (- 3) (5) (- 4)

Apply rule

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

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

= - 15 (5) (- 4)

15 (5) = 75

15 (5)

Apply rule:

(a) = a

(5) = 5

= 15 \cdot 5

Multiply the numbers:

15 \cdot 5 = 75

= 75

= 75 (- 4)

Apply rule

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

75 (- 4) = - 75 \cdot 4 = - 300

= - 300

= 12 - (- 2) - (- 300)

Add and subtract (left to right)

12 - (- 2) - (- 300) : 314

12 - (- 2) - (- 300)

Apply rule

- (- a) = + a

- (- 2) = + 2

= 12 + 2 - (- 300)

12 + 2 = 14

= 14 - (- 300)

Apply rule

- (- a) = + a

- (- 300) = + 300

= 14 + 300

14 + 300 = 314

= 314

= 314

- 3 (2) - 2

- 3 (2) + 8

(41 \cdot 35)^{3}

(2 - 4)^{2} - 1

\frac{20}{4} - 5 + \frac{15}{5}
