1 + (1 - (- 1 - (- 1) - 1 + 1 + (- 1)))

3

Solution steps

1 + (1 - (- 1 - (- 1) - 1 + 1 + (- 1)))

Follow the PEMDAS order of operations

Calculate within parentheses

(1 - (- 1 - (- 1) - 1 + 1 + (- 1))) : 2

1 - (- 1 - (- 1) - 1 + 1 + (- 1))

Calculate within parentheses

(- 1 - (- 1) - 1 + 1 + (- 1)) : - 1

- 1 - (- 1) - 1 + 1 + (- 1)

Add and subtract (left to right)

Apply rule

- (- a) = + a

- (- 1) = + 1

= - 1 + 1 - 1 + 1 + (- 1)

- 1 + 1 = 0

= 0 - 1 + 1 + (- 1)

0 - 1 = - 1

= - 1 + 1 + (- 1)

- 1 + 1 = 0

= 0 + (- 1)

Apply rule

+ (- a) = - a

+ (- 1) = - 1

= 0 - 1

0 - 1 = - 1

= - 1

= 1 - (- 1)

Add and subtract (left to right)

1 - (- 1) : 2

1 - (- 1)

Apply rule

- (- a) = + a

- (- 1) = + 1

= 1 + 1

1 + 1 = 2

= 2

= 2

= 1 + 2

Add and subtract (left to right)

1 + 2 : 3

1 + 2

1 + 2 = 3

= 3

= 3

7 \div 7 - 4 \times 5 - (- 10)

- 2 + 10 (- 4 + 3) (2) (- 4) (- 7) (- 3 \times 1)

3 - 1 - 3 + 5 - 2 + 6

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

1 - 1 + 3
