((-9)/(-3))-2[-3-(12-7)]

(\frac{- 9}{- 3}) - 2 [- 3 - (12 - 7)]

19

Solution steps

(\frac{- 9}{- 3}) - 2 [- 3 - (12 - 7)]

Simplify

\frac{- 9}{- 3} : 3

Apply the fraction rule:

\frac{- a}{- b} = \frac{a}{b}

= \frac{9}{3}

Divide the numbers:

\frac{9}{3} = 3

= 3

= 3 - 2 [- 3 - (12 - 7)]

Follow the PEMDAS order of operations

Calculate within parentheses

[- 3 - (12 - 7)] : - 8

- 3 - (12 - 7)

Calculate within parentheses

(12 - 7) : 5

12 - 7

12 - 7 = 5

= 5

= - 3 - 5

Add and subtract (left to right)

- 3 - 5 : - 8

- 3 - 5

- 3 - 5 = - 8

= - 8

= - 8

= 3 - 2 (- 8)

Multiply and divide (left to right)

2 (- 8) : - 16

2 (- 8)

Apply rule

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

2 (- 8) = - 2 \cdot 8 = - 16

= - 16

= 3 - (- 16)

Add and subtract (left to right)

3 - (- 16) : 19

3 - (- 16)

Apply rule

- (- a) = + a

- (- 16) = + 16

= 3 + 16

3 + 16 = 19

= 19

= 19

6 0^{2} + 4 5^{2}

- 4^{3} + 8 \cdot 11 \div 4

(+ 9) + (+ 5) - (- 6) + (- 4) - (+ 7) + (- 6)

- 1 \times (- 1) \times 1

(4 \times 4 \div 2) \div (8 - 3 \times 2)
