How to learn to add quickly- It is essential to learn to do quick math mentally rather than using a calculator. It helps improve your counting skills and enables you to save time while increasing your mental capability.
Can you count the below numbers in 5 seconds?

7 +5 +6 +4 +3 +8 +1 +4 =?

Your answer is most probably 38. If you couldn’t do it in five seconds, then don’t worry. Here are a few tips for you.
The best trick of learning to add quickly is looking for complements, i.e., if you have a number 9, then you look for its complement 1. It will help you add numbers mentally. So, if we make a list of all complements it would be:

1 for 9

2 for 8

3 for 7

4 for 6

5 for 5

These numbers, when added with their complements, then you can the number 10.
If you are adding double digit numbers such as:

21 + 36 + 33 + 61 =?

The answer is 151. A great way of dealing with double-digit addition is breaking them down into tens and one i.e.

20 + 1

30 + 3

30 + 6

60 + 1
It will greatly help you add numbers more effectively.
These worksheets are great to flex your addition muscles.
