Solve -(60(-390)+102(-286))-(5(-159)+74(-171.8))

$$- ( 60 ( - 390 ) + 102 ( - 286 ) ) - ( 5 ( - 159 ) + 74 ( - 171.8 ) )$$

Evaluate

$$66080.2$$

Solution Steps

Multiply 60 and -390 to get -23400. Multiply 102 and -286 to get -29172.

$$-\left(-23400-29172\right)-\left(5\left(-159\right)+74\left(-171.8\right)\right)$$

Subtract 29172 from -23400 to get -52572.

$$-\left(-52572\right)-\left(5\left(-159\right)+74\left(-171.8\right)\right)$$

The opposite of -52572 is 52572.

$$52572-\left(5\left(-159\right)+74\left(-171.8\right)\right)$$

Multiply 5 and -159 to get -795.

$$52572-\left(-795+74\left(-171.8\right)\right)$$

Multiply 74 and -171.8 to get -12713.2.

$$52572-\left(-795-12713.2\right)$$

Subtract 12713.2 from -795 to get -13508.2.

$$52572-\left(-13508.2\right)$$

The opposite of -13508.2 is 13508.2.

$$52572+13508.2$$

Add 52572 and 13508.2 to get 66080.2.

$$66080.2$$

Factor

$$\frac{163 \cdot 2027}{5} = 66080\frac{1}{5} = 66080.2$$
