Day 14: Understanding Subtraction

Introduction

If I have ten cars and I give my friend three cars, how many cars do I have left? I have seven cars left. We learned that you can count on to add two groups. In subtraction, you count backward to get the total that is left over. We learned about counting backward in a previous module. For the problem I just shared, you would start at 10 and count backward 3 numbers. Ten minus three is seven.
