Follow the PEMDAS order of operations

Calculate exponents

(- 7)^{2} : 49

(- 7)^{2}

Apply exponent rule:

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

n

is even

(- 7)^{2} = 7^{2} = 49

= 49

= 49 + 5 (- 7)

Multiply and divide (left to right)

5 (- 7) : - 35

5 (- 7)

Apply rule

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

5 (- 7) = - 5 \cdot 7 = - 35

= - 35

= 49 - 35

Add and subtract (left to right)

49 - 35 : 14

49 - 35

49 - 35 = 14

= 14

= 14

- 6^{3} \cdot (- 3^{3})

2^{3} + (- 1)^{10} + (- 3)^{2}

3 [- 3] + 8 [- 3]^{2} (5 [0]^{2} [- 3])

2 \cdot 3 - 5/7 + 3

\frac{( 6 \cdot 4 + 0 )}{5}
