Solve -1-2+7+3-(-8-8+14-1,5)=

$$- 1 - 2 + 7 + 3 - ( - 8 - 8 + 14 - 1,5 ) =$$

Evaluate

$$10,5$$

Solution Steps

Subtract 2 from -1 to get -3.

$$-3+7+3-\left(-8-8+14-1,5\right)$$

Add -3 and 7 to get 4.

$$4+3-\left(-8-8+14-1,5\right)$$

Add 4 and 3 to get 7.

$$7-\left(-8-8+14-1,5\right)$$

Subtract 8 from -8 to get -16.

$$7-\left(-16+14-1,5\right)$$

Add -16 and 14 to get -2.

$$7-\left(-2-1,5\right)$$

Subtract 1,5 from -2 to get -3,5.

$$7-\left(-3,5\right)$$

The opposite of -3,5 is 3,5.

$$7+3,5$$

Add 7 and 3,5 to get 10,5.

$$10,5$$

Factor

$$\frac{3 \cdot 7}{2} = 10\frac{1}{2} = 10.5$$
