What is Called Adding
When one or more numbers or digits are added to a number or Digit, it is called addition.
Addition is shown with a + sign.
Example :-
- 5 + 5 = 10
- 10 + 10 = 20
- 25 + 25 = 50
- 50 + 50 = 100
- 100 + 100 = 200
Add (Verbal)
The numbers which have zero at the end (unit) are called zero numbers.
like :
10, 20, ………………….
100, 200, ………………….
1000, 2000, ………………….
Adding other numbers to numbers with zero is easy.

FAQ
Ans. Addition in math is a process of combining two or more numbers.
Ans. Let us take a look at these strategies:
1. Addition using an open number line.
2. Addition using partial sum.
3. Addition using regrouping.
4. Addition using the compensation method.
5. Addition using models.
Ans. Commutative property of addition : Changing the order of addends does not change the sum.
For example, 4 + 2 = 2 + 4 . Associative property of addition: Changing the grouping of addends does not change the sum. For example, ( 2 + 3 ) + 4 = 2 + ( 3 + 4 ) .
Ans. This is called an addition formula because of the sum A + B appearing the formula. Note that it enables us to express the sine of the sum of two angles in terms of the sines and cosines of the individual angles. Key Point. sin(A + B) = sin A cosB + cosA sin B.
Ans. What is the Zero Property of Addition? The zero property of addition is another name for the identity property of addition. It states that if any number is added to 0, the sum is the number itself. For example, 835 + 0 = 835.
