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

- 1

Solution steps

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

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

= 1 + 3 (- 1) + 1

Multiply and divide (left to right)

3 (- 1) : - 3

3 (- 1)

Apply rule

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

3 (- 1) = - 3 \cdot 1 = - 3

= - 3

= 1 - 3 + 1

Add and subtract (left to right)

1 - 3 + 1 : - 1

1 - 3 + 1

1 - 3 = - 2

= - 2 + 1

- 2 + 1 = - 1

= - 1

= - 1

- 2 (0)^{2} + 5 - 0

2 \div 2 + 4 \times 5 - 4 \times 2 + 27 \div 3

\frac{22 + 1 ^{3} + ( 3 ^{4} - 7 ^{2} )}{2 ^{3}}

(- 1)^{2} + 3 (- 1) - 4

36 \div 3 \times (8 - 6) \div 6
