-3-(-2)\times 4+20\div (-4)+(-1)

- 3 - (- 2) \times 4 + 20 \div (- 4) + (- 1)

- 1

Solution steps

- 3 - (- 2) \times 4 + 20 \div (- 4) + (- 1)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

(- 2) \times 4 : - 8

(- 2) \times 4

Apply rule

(- a) \times b = - a \times b

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

= - 8

= - 3 - (- 8) + 20 \div (- 4) + (- 1)

Multiply and divide (left to right)

20 \div (- 4) : - 5

20 \div (- 4)

Apply rule

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

20 \div (- 4) = - 20 \div 4 = - 5

= - 5

= - 3 - (- 8) - 5 + (- 1)

Add and subtract (left to right)

- 3 - (- 8) - 5 + (- 1) : - 1

- 3 - (- 8) - 5 + (- 1)

Apply rule

- (- a) = + a

- (- 8) = + 8

= - 3 + 8 - 5 + (- 1)

- 3 + 8 = 5

= 5 - 5 + (- 1)

5 - 5 = 0

= 0 + (- 1)

Apply rule

+ (- a) = - a

+ (- 1) = - 1

= 0 - 1

0 - 1 = - 1

= - 1

= - 1

(+ 1) + (- 3) + (- 4) + (+ 7)

3 (2)^{2} - 5

12 + 6^{3} - (15 - 6)^{2} + 2

(7 + 3 \frac{1}{8}) \div (14 + 6 \frac{1}{4})

20 - 5 (27 \div 3)
