Answer 1

To find \(-123.45 - (-234.76)\) using the additive inverse, we can rewrite the expression. The additive inverse of \(-234.76\) is \(+234.76\).

So, the expression becomes:

\[ -123.45 + 234.76 \]

Now, we can perform the addition:

\[ 234.76 - 123.45 \]

To calculate this, we can align the numbers:

  234.76
- 123.45
---------

Now performing the subtraction:

• In the hundredths place: \(6 - 5 = 1\)
• In the tenths place: \(7 - 4 = 3\)
• In the units place: \(4 - 3 = 1\)
• In the tens place: \(3 - 2 = 1\)
• In the hundreds place: \(2 - 1 = 1\)

Putting it all together, we get:

\[ 234.76 - 123.45 = 111.31 \]

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

\[ \boxed{111.31} \]
