Answer:
x + 3
Step-by-step explanation:
A 'sum' means addition, 'a number' is represented by a variable, in this case, I chose 'x'. I could have picked any variable I wanted.
The sum of three and a number means: three plus some number, which is
3 + x in math language. We write variables before constants, so it gets
rewritten as x + 3
