Adding and Subtracting Fractions on the Number Line

The video tutorial explains how to use a number line to understand fractions. It begins with numbering a number line by dividing it into equal parts. The tutorial then demonstrates subtracting fractions, using the example of subtracting 3/4 from 1 and 3/8, and shows how to locate these fractions on the number line. The process involves moving left for subtraction. Next, the video covers adding fractions, using the example of adding 7/8 and 1/4, and explains how to move right on the number line for addition.
