7-16+(-5)-(-12)+(-8)-15-3

7 - 16 + (- 5) - (- 12) + (- 8) - 15 - 3

- 28

Solution steps

7 - 16 + (- 5) - (- 12) + (- 8) - 15 - 3

Follow the PEMDAS order of operations

Add and subtract (left to right)

7 - 16 = - 9

= - 9 + (- 5) - (- 12) + (- 8) - 15 - 3

Apply rule

+ (- a) = - a

+ (- 5) = - 5

= - 9 - 5 - (- 12) + (- 8) - 15 - 3

- 9 - 5 = - 14

= - 14 - (- 12) + (- 8) - 15 - 3

Apply rule

- (- a) = + a

- (- 12) = + 12

= - 14 + 12 + (- 8) - 15 - 3

- 14 + 12 = - 2

= - 2 + (- 8) - 15 - 3

Apply rule

+ (- a) = - a

+ (- 8) = - 8

= - 2 - 8 - 15 - 3

- 2 - 8 = - 10

= - 10 - 15 - 3

- 10 - 15 = - 25

= - 25 - 3

- 25 - 3 = - 28

= - 28

- (- 2)^{2} + 1

54 - (15 - 31) + (- 27)

\frac{2 ^{0} - ( - 2 ) ^{2}}{2 ^{2} + ( - 2 ) ^{3}}

6^{2} + 1 0^{2}

1^{2} + 2^{2} + 3^{2}
