The letters are variables that represent an unknown number. You can solve for the variables and find their value. Calculations for many tasks would be impossible without variables.
you don't have to use numbers, the question mark was the first variable mentioning an unknown value. you could use a smiley face or a banana as your variable. it doesn't matter!
