Such a translation is made by "explaining" what the expression is telling you to do, paying attention to the order in which the operations are made.
For example, an expression like [tex]7n+2[/tex] can be translated as "the sum of seven times a number and 2"
Or an expression like [tex](5+3)\cdot 2[/tex] can be translated as "the product of 2 and the sum of 5 and 3".
