Answer
$-1.1$
Work Step by Step
The addends (numbers being added have) different signs.
To add two numbers with different signs, perform the following steps:
(1) Subtract the smaller absolute from the bigger absolute value.
$|-6.3|-|5.2|=6.3-5.2=1.1$
(2) Use the sign of the number with the bigger absolute value.
$-6.3+5.2=-1.1$
Thus, the sum is $-1.1$.
