Solve 5,1+8,4-(-5,1)-10,2-(+8,4)-9,8-(-15)

$$5,1 + 8,4 - ( - 5,1 ) - 10,2 - ( + 8,4 ) - 9,8 - ( - 15 )$$

Evaluate

$$5,2$$

Solution Steps

Add 5,1 and 8,4 to get 13,5.

$$13,5-\left(-5,1\right)-10,2-8,4-9,8-\left(-15\right)$$

The opposite of -5,1 is 5,1.

$$13,5+5,1-10,2-8,4-9,8-\left(-15\right)$$

Add 13,5 and 5,1 to get 18,6.

$$18,6-10,2-8,4-9,8-\left(-15\right)$$

Subtract 10,2 from 18,6 to get 8,4.

$$8,4-8,4-9,8-\left(-15\right)$$

Subtract 8,4 from 8,4 to get 0.

$$-9,8-\left(-15\right)$$

The opposite of -15 is 15.

$$-9,8+15$$

Add -9,8 and 15 to get 5,2.

$$5,2$$

Factor

$$\frac{2 \cdot 13}{5} = 5\frac{1}{5} = 5.2$$
