# Pre-algebra word problems | Lesson

## What are pre-algebra word problems?

Pre-algebra word problems are questions that require translating sentences to expressions, then evaluating those expressions.

The expressions we need to write will involve numbers and operations, but no variables.

### What skills are tested?

- Solving real world problems by identifying relevant numbers and operations
- Identifying contexts where the answer must be rounded up or down

## How do we solve pre-algebra word problems?

Solving pre-algebra word problems requires us to create expressions and evaluate them.

To solve a pre-algebra word problem:

- Identify the quantity to be calculated.
- Determine the operations and numbers needed to calculate the desired quantity.
- Write and evaluate the expressions to get the desired quantity.
- If the context requires rounding, round the answer.
