Question

-6.54 + (-2.23)

Answer 1

To add the two numbers, you combine them as follows:

\[
-6.54 + (-2.23) = -6.54 - 2.23
\]

Now, we can add the absolute values of the numbers:

\[
6.54 + 2.23 = 8.77
\]

Since both original numbers were negative, the result will also be negative:

\[
-6.54 + (-2.23) = -8.77
\]

Thus, the final answer is \(-8.77\).
