Solve 5(8-9)-8(5-9)+4(5+6)=

$$5(8-9)-8(5-9)+4(5+6)=$$

Evaluate

$$71$$

Solution Steps

Subtract 9 from 8 to get -1.

$$5\left(-1\right)-8\left(5-9\right)+4\left(5+6\right)$$

Multiply 5 and -1 to get -5.

$$-5-8\left(5-9\right)+4\left(5+6\right)$$

Subtract 9 from 5 to get -4.

$$-5-8\left(-4\right)+4\left(5+6\right)$$

Multiply 8 and -4 to get -32.

$$-5-\left(-32\right)+4\left(5+6\right)$$

The opposite of -32 is 32.

$$-5+32+4\left(5+6\right)$$

Add -5 and 32 to get 27.

$$27+4\left(5+6\right)$$

Add 5 and 6 to get 11.

$$27+4\times 11$$

Multiply 4 and 11 to get 44.

$$27+44$$

Add 27 and 44 to get 71.

$$71$$

Factor
