Your question isn't well written, but I saw something similar online.
Yesterday, Leila had M baseball cards. Today, she got 11 more. Using M, write an expression for the total number of baseball cards she has now.
For us to solve this question, we have to add the number of baseball cards that she had yesterday plus the number of baseball cards that she had today. This will be:
= M + 11
Therefore, the expression for the total number of baseball cards she has now is M + 11.
