In basic arithmetic, 1 + 1 equals 2 because when you combine one unit with another unit, you end up with a total of two units. Similarly, 2 + 1 equals 3 because when you add two units to one more unit, the total number of units becomes three. These equations follow the fundamental principles of addition, where the sum represents the total quantity when two or more numbers are combined. **
