Use the additive inverse to find -123.45 -(-234.76)
The additive inverse of a number is the number that, when added to the original number, equals zero. The additive inverse of a positive number is the negative version of that number, and the additive inverse of a negative number is the positive version of that number.
To find -123.45 -(-234.76), we need to convert the subtraction of the second term into addition using the additive inverse. This means changing the operation from subtraction to addition and changing the sign of the second term.
So, -123.45 -(-234.76) becomes -123.45 + 234.76.
Now, we can add the two numbers:
-123.45 + 234.76 = 111.31
Therefore, -123.45 -(-234.76) is equal to 111.31.
