Question

Find -37.6 + ( - 3.9) + ( -10) .

Answer 1

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
