17-7*(-4)

Solution

17 - 7 \cdot (- 4)

45

Solution steps

17 - 7 (- 4)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

7 (- 4) : - 28

7 (- 4)

Apply rule

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

7 (- 4) = - 7 \cdot 4 = - 28

= - 28

= 17 - (- 28)

Add and subtract (left to right)

17 - (- 28) : 45

17 - (- 28)

Apply rule

- (- a) = + a

- (- 28) = + 28

= 17 + 28

17 + 28 = 45

= 45

= 45

+ (0 - (- 1))

4 \times 35 + 3 \times 28 + 2 \times 25

- 3 - 8 \times 5

2 (2)^{2} - (5)^{3} - (- 3)^{3} - (- 1)^{5}

3 - 6 \times (5 - 7)
