When you subtract a negative number, it is equivalent to adding its positive counterpart. This can be understood using the following rule in mathematics:

- **Subtracting a negative number is the same as adding the positive version of that number.**

So, in your example:

\[
103 - (-2)
\]

The subtraction of \(-2\) can be rewritten as the addition of \(+2\). Therefore:

\[
103 - (-2) = 103 + 2
\]

This simplification works because subtracting a negative number moves you to the right on the number line, which is the same as adding the positive number.
