Solve 1(-25-(-28))-2(-10-(-14))+3(-10-(-8))

$$1 ( - 25 - ( - 28 ) ) - 2 ( - 10 - ( - 14 ) ) + 3 ( - 10 - ( - 8 ) )$$

Evaluate

$$-11$$

Solution Steps

The opposite of -28 is 28.

$$1\left(-25+28\right)-2\left(-10-\left(-14\right)\right)+3\left(-10-\left(-8\right)\right)$$

Add -25 and 28 to get 3.

$$1\times 3-2\left(-10-\left(-14\right)\right)+3\left(-10-\left(-8\right)\right)$$

Multiply 1 and 3 to get 3.

$$3-2\left(-10-\left(-14\right)\right)+3\left(-10-\left(-8\right)\right)$$

The opposite of -14 is 14.

$$3-2\left(-10+14\right)+3\left(-10-\left(-8\right)\right)$$

Add -10 and 14 to get 4.

$$3-2\times 4+3\left(-10-\left(-8\right)\right)$$

Multiply 2 and 4 to get 8.

$$3-8+3\left(-10-\left(-8\right)\right)$$

Subtract 8 from 3 to get -5.

$$-5+3\left(-10-\left(-8\right)\right)$$

The opposite of -8 is 8.

$$-5+3\left(-10+8\right)$$

Add -10 and 8 to get -2.

$$-5+3\left(-2\right)$$

Multiply 3 and -2 to get -6.

$$-5-6$$

Subtract 6 from -5 to get -11.

$$-11$$

Factor
