- 3^{2} + 6 (- 3) (4)

- 81

Solution steps

- 3^{2} + 6 (- 3) (4)

Follow the PEMDAS order of operations

Calculate exponents

3^{2} : 9

3^{2}

3^{2} = 9

= 9

= - 9 + 6 (- 3) (4)

Multiply and divide (left to right)

6 (- 3) (4) : 72

6 (- 3) (4)

Apply rule

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

6 (- 3) = - 6 \cdot 3 = - 18

= - 18 (4)

18 (4) = 72

18 (4)

Apply rule:

(a) = a

(4) = 4

= 18 \cdot 4

Multiply the numbers:

18 \cdot 4 = 72

= 72

= 72

= - 9 - 72

Add and subtract (left to right)

- 9 - 72 : - 81

- 9 - 72

- 9 - 72 = - 81

= - 81

= - 81

4 \times 2^{3} - 3 \times 3 + 5 \times (4 + 3)

\frac{1}{2} - 3 - 1

(5/19) / [(15/20) + (5/19)]

144 - 8 + 6

2^{4} + 3 (2) - 10
