الأعداد الصحيحة: الجمع والطرح على خط الأعداد

The video tutorial explains how to perform addition and subtraction on a number line. It begins with an introduction to the concept, using the number six as a starting point. The tutorial demonstrates adding four to six, resulting in ten, and then subtracting four to return to six. It further explores using larger numbers, such as adding ten to six to get sixteen, and then subtracting ten to return to six. The key insight is that adding and then subtracting the same number brings you back to the starting point.
