Follow the PEMDAS order of operations

Calculate within parentheses

(- 2 - 3) : - 5

- 2 - 3

- 2 - 3 = - 5

= - 5

= (- 5)^{2} - 2

Calculate exponents

(- 5)^{2} : 25

(- 5)^{2}

Apply exponent rule:

(- a)^{n} = a^{n},

n

is even

(- 5)^{2} = 5^{2} = 25

= 25

= 25 - 2

Add and subtract (left to right)

25 - 2 : 23

25 - 2

25 - 2 = 23

= 23

= 23

5 - 6 (- 2) - 20

(\frac{9}{8} - \frac{7}{8}) + \frac{10}{8}

45 \div 15 + 2 \times 2 + 24 \div 12 - 16 \div 4 + 1

- \frac{1}{2} (- 1)^{3}

- 5^{2} - 8 (- 5) + 4
