$-1.1$
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 $-1.1$.
