To solve the calculation, the first step is to simplify the signs. When a plus and a minus are next to each other, the plus sign is canceled, You can say that "plus by minus equals minus" so that:


-37.6+(-3.9)+(-10)=-37.6-3.9-10

This means that you have to subtract 3.9 and 10 from -37.6. When you subtract numbers to a negative value, is the same as adding the absolute values of each number, remember that the result has to be negative. Start from left to right:


\begin{gathered} -37.6-3.9-10 \\ -(37.6+3.9)-10 \\ -41.5-10 \\ -(41.5+10)=-51.5 \end{gathered}

The result of the operation is -51.5
