Use the additive inverse to find - 123.45 - (-234.76). (1 point)

When we subtract a negative number, it is the same as adding the positive version of that number.

Therefore, we can rewrite the expression as -123.45 + 234.76.

Now, we can solve for the sum.

-123.45 + 234.76 = 111.31

The answer is 111.31.

To find the addition of two numbers when one of them is a negative number, we can use the concept of additive inverse.

The additive inverse of a number is the number that, when added to the original number, gives a sum of zero. For any number 'a', its additive inverse is represented as '-a'.

In this case, we are asked to find the value of '-123.45 - (-234.76)'. To solve this, we can consider the second negative number as its additive inverse.

So, '-123.45 - (-234.76)' can be rewritten as '-123.45 + 234.76'.

Now we can simply add these two numbers: -123.45 + 234.76 = 111.31.

Therefore, '-123.45 - (-234.76)' is equal to 111.31.

To find the value of -123.45 - (-234.76) using the additive inverse, you can follow these steps:

Step 1: Change the subtraction into addition by changing the sign of the second number.
-123.45 + 234.76

Step 2: Add the two numbers together.
-123.45 + 234.76 = 111.31

Therefore, -123.45 - (-234.76) is equal to 111.31.
