-2+3\times 5-4\times (-10)+1

- 2 + 3 \cdot 5 - 4 \cdot (- 10) + 1

54

Solution steps

- 2 + 3 \cdot 5 - 4 (- 10) + 1

Follow the PEMDAS order of operations

Multiply and divide (left to right)

3 \cdot 5 : 15

3 \cdot 5

3 \cdot 5 = 15

= 15

= - 2 + 15 - 4 (- 10) + 1

Multiply and divide (left to right)

4 (- 10) : - 40

4 (- 10)

Apply rule

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

4 (- 10) = - 4 \cdot 10 = - 40

= - 40

= - 2 + 15 - (- 40) + 1

Add and subtract (left to right)

- 2 + 15 - (- 40) + 1 : 54

- 2 + 15 - (- 40) + 1

- 2 + 15 = 13

= 13 - (- 40) + 1

Apply rule

- (- a) = + a

- (- 40) = + 40

= 13 + 40 + 1

13 + 40 = 53

= 53 + 1

53 + 1 = 54

= 54

= 54

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

1 \frac{4}{5} \div (17 - 8)

14 - 25 + (32 \div (- 2)) (- 5) + 6 (- 1 - 3)^{2}

5 - 3 [7 + 6 (- 9 + 7)]

(32 + 10) \times 5
