The algebraic expression is $x + 10$.
To represent a number, choose a letter (I chose $x$). The phrase "added to" means plus. Now, you can rewrite the expression:
stackrel(x) overbrace("A number") " " stackrel(+) overbrace("added to") " " stackrel(10) overbrace("10") "."
The final expression is $x + 10$.
