Solution

3 (- 1)^{2} - 5

- 2

Solution steps

3 (- 1)^{2} - 5

Follow the PEMDAS order of operations

Calculate exponents

(- 1)^{2} : 1

(- 1)^{2}

Apply exponent rule:

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

n

is even

(- 1)^{2} = 1^{2} = 1

= 1

= 3 \cdot 1 - 5

Multiply and divide (left to right)

3 \cdot 1 : 3

3 \cdot 1

3 \cdot 1 = 3

= 3

= 3 - 5

Add and subtract (left to right)

3 - 5 : - 2

3 - 5

3 - 5 = - 2

= - 2

= - 2

2 (- 2) + 2 (- 3)

10 \div (3 + 2) \times 4 + 5^{2} + 6 - 9

- \frac{\frac{8}{- 1}}{( - 6 - 2 )}

1^{2} + 6^{2}

4 (1) - 3
