(30\div (-3)\times 2)-(30+(21)\div 3)

(30 \div (- 3) \times 2) - (30 + (21) \div 3)

- 57

Solution steps

(30 \div (- 3) \times 2) - (30 + (21) \div 3)

Follow the PEMDAS order of operations

Calculate within parentheses

(30 \div (- 3) \times 2) : - 20

30 \div (- 3) \times 2

Multiply and divide (left to right)

Apply rule

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

30 \div (- 3) = - 30 \div 3 = - 10

= - 10 \times 2

- 10 \times 2 = - 20

= - 20

= - 20 - (30 + (21) \div 3)

Calculate within parentheses

(30 + (21) \div 3) : 37

30 + (21) \div 3

Multiply and divide (left to right)

(21) \div 3 : \frac{( 21 )}{3}

(21) \div 3

(21) \div 3 = \frac{( 21 )}{3}

= \frac{( 21 )}{3}

= 30 + \frac{( 21 )}{3}

Add and subtract (left to right)

30 + \frac{( 21 )}{3} : 37

30 + \frac{( 21 )}{3}

30 + \frac{( 21 )}{3} = 37

30 + \frac{21}{3}

Divide the numbers:

\frac{21}{3} = 7

= 30 + 7

Add the numbers:

30 + 7 = 37

= 37

= 37

= 37

= - 20 - 37

Add and subtract (left to right)

- 20 - 37 : - 57

- 20 - 37

- 20 - 37 = - 57

= - 57

= - 57

\frac{( 3 6 ^{5} - 3 6 ^{8} )}{17}

2 (8 - 4 (3 [1 + 2]))

1 - 0^{2}

8 - 5 \cdot 4^{2}

- 1^{3} - 1
