# Whole Number Operations (A4301)

## Prerequisites

This lesson is designed so that no prior knowledge is required.

## Description

This lesson reviews the basic concepts of comparing, rounding, adding, subtracting, multiplying, and dividing whole numbers. It also reviews the steps for solving addition, subtraction, multiplication, and division problems. Participants learn about using estimating techniques and the calculator to solve mathematical problems. Participants also learn about a basic problem-solving strategy that can be applied to solve many mathematical problems.

## Objectives
