Creating a word problem for an expression involves interpreting each number, operation, and grouping symbol as a meaningful quantity or relationship, using contexts such as combining, comparing, equal groups, rates, or sharing. The situation must preserve the expression’s order of operations—for example, distinguishing a quantity multiplied by a sum from a product plus another quantity—and use appropriate whole-number, decimal, or fraction values. This connects verbal modeling with later algebraic representation.

To create a word problem for an expression:
Suppose the expression is
The parentheses mean that happens first. This could represent two types of objects being combined:
So, each group has
apples.
The outside the parentheses means there are 4 equal groups of the combined amount.
A grocery store makes 4 bags of fruit. Each bag contains 3 red apples and 2 green apples. How many apples are in all 4 bags?
Each bag contains apples, and there are 4 bags:
So, there are 20 apples altogether.
Be careful not to write a situation that means . That expression would describe 4 groups of 3 apples, with 2 more apples added afterward—not 4 groups that each contain both 3 apples and 2 apples.
