To clarify, the expression you provided is:

\[
2^2 \pm 1 + 3
\]

This notation can be interpreted as having both a positive and negative version of the equation:

### Version 1: With a plus sign
\[
2^2 + 1 + 3 = 4 + 1 + 3 = 8
\]

### Version 2: With a minus sign
\[
2^2 - 1 + 3 = 4 - 1 + 3 = 6
\]

So, depending on the operation you choose, the results can be:
- **8** for the plus version.
- **6** for the minus version.
