We have to add two units of elements, and the result will be the sum of that mathematical operation which is called addition.
1. Now, if we have two elements, like two apples, we have:
2. Now, the sum of these apples can be represented as an addition operation, and this operation uses the plus sign ( + ) to add these two elements:
3. Now, we can say that the sum of the apples is 2. If we count them, we will have the same result:
Therefore, in summary, we can say that 1 + 1 = 2.
