How do you write down an expression?
Ex. 3*5+2 3*6+2 3*8+2 3*4+2 3*3+2 3*2+2 3*10+2
Expression:
3a+2

You show us two expressions and then ask how to write an expression. I must be missing something here.
An expression is a collection of terms, joined by + or  signs.
each term is a product, where factors are joined by * or / signs.
Factors may include a unary minus sign.
