 Question from mayra, a student: the sum of a number p and twenty-one

Hi Mayra,

Have a look at something I just posted. The question is different but it deals with an algebraic expression with a letter representing an unknown number. The letter in that question is $x$ and the letter in your question is $p.$

Please write back if you need more assistance,
Penny
