Why do letters belong in math?

Asked by Alijah Chávez

Letters are used to replace some of the numbers where a numerical expression would be too complicated, or where you want to generalise rather than use specific numbers. They can also be used when you know the values in part of the equation, but others are unknown and you need to work them out.
