Question

Use the additive inverse to find −123.45−(−234.76) .

Answer 1

un numbers only

Answer 2

in numbers only

Answer 3

To calculate \(-123.45 - (-234.76)\) using the concept of the additive inverse, we can first rewrite the expression:

\[
-123.45 - (-234.76) = -123.45 + 234.76
\]

Now, we simply add \(-123.45\) and \(234.76\):

1. Align the numbers:
\[
\begin{array}{r}
-123.45 \\
+234.76 \\
\hline
\end{array}
\]

2. Add the numbers:
- When adding, we can separate the addition into two parts (the whole numbers and the decimals):
- First, we deal with the whole number part: \(234 + (-123) = 234 - 123 = 111\)
- Then, for the decimal part: \(0.76 + (-0.45) = 0.76 - 0.45 = 0.31\)

3. Thus, adding the whole number and decimal results:
\[
111 + 0.31 = 111.31
\]

Therefore, the final result of \(-123.45 - (-234.76)\) is:

\[
\boxed{111.31}
\]
