Introduction of Addition Table
The term Arithmetic Addition in mathematics refers to adding two or more numbers together for forming the addition table and the mathematics symbol or operator, which denotes that the addition is the + plus sign, for example - 8 + 4 = 12.
The term Sum also denotes the same operation of addition. We can use the summation symbol “∑” for denoting the addition of a series of numbers.
Understanding the Addition Table
Now, let us have a better understanding of using the addition table. Suppose you want to add 5 and 3, that is, 5 + 3. All you have to do is go down to the row, which has the number “5” written on it and then along the column, which has the number “3” written on it to get your answer, which is 8. As we know that the mathematical operation of arithmetic addition is commutative, you can also go down the row, which has the number “3” written on it, and then along the column, which has the number “5” written on it to get your answer, which is again 8 (5 + 3 = 3 + 5).

Easy and Quick Tips to Keep in Mind for Performing Addition
If we add 0 to a number, then it makes no difference, for example - 7 + 0 = 7, 6 + 0 = 6, 89 + 0 = 0.
If we add a group of numbers together, the answer will be the same, irrespective of their order or sequence, for example - 8 + 7 + 3 + 2 = 20 and 7 + 2 + 3 + 8 = 20.
For performing the mathematical operation of addition on a long list of numbers, we arrange the numbers in a column and then obtain the result easily.
If we add 1 to an even number, then the result is an added number, for example - 4 + 1 = 5, 8 + 1 = 9.
If we add two even numbers, then the result is also an even number, for example - 8 + 2 = 10, 6 + 4 = 10.
If we add 1 to a number, then the result is the next number after the number in the question, for example - 7 + 1 = 8, 5 + 1 = 6.
