Use the additive inverse to find - 123.45 - (--234.76)

Question

O 121.31
O -111.31
O 111.31
O 358.21

Answer 1

To solve the expression \(-123.45 - (--234.76)\), we can first simplify it using the additive inverse.

The expression \(-(--234.76)\) is equivalent to \(+234.76\) because the double negative cancels out.

So, the expression simplifies to:

\[ -123.45 + 234.76 \]

Now, we can perform the addition:

1. First, we find the difference between \(234.76\) and \(123.45\):

\[ 234.76 - 123.45 = 111.31 \]

Thus,

\[ -123.45 - (--234.76) = 111.31 \]

The correct answer is:

111.31
