1. The problem is to evaluate the expression $m - m + 3$ when $m = 1$.
2. The expression is $m - m + 3$.
3. Substitute $m = 1$ into the expression:
$$1 - 1 + 3$$
4. Simplify the expression step-by-step:
$$\cancel{1} - \cancel{1} + 3 = 0 + 3$$
5. Add the remaining terms:
$$0 + 3 = 3$$
6. Therefore, the value of the expression when $m = 1$ is $3$.
