Addition of Big Numbers
Adding numbers is relatively easy, even in our heads, but only as long as they are small digits. When adding large numbers, it always becomes difficult to add them in our heads. Therefore, here is a trick that will make it easy for you to add 2 large numbers in your head quickly. Letโs see an example now.
How to add a large number in your head very fast – โ544 + 338โ
- We know itโs a bit difficult to add them in your head fast. So, what you need to do instead is round them up first to make them manageable. So, 544 becomes 550, and 338 becomes 340.
- Now, you can add 550 and 340 in your head, and that too pretty fast. The total will be 890.
- Now, determine how much you initially added to your original numbers.
- So, 550 – 544 = 6 and 340 โ 338 = 2
- Now, after adding these, the total is 8
- The final answer will be found by subtracting this from 890.
890 โ 8 = 882
We know that you might think this is such a lengthy procedure. But no. This seems long becomes youโre seeing it in writing. When you actually try and solve it in your head like this, this math problem will be pretty easy and fast.

Subtraction from 1,000
So, when you subtract a significant number from 1000, all you need to do is subtract all the numbers except the last one from 9 and the last one from 10. Hereโs an example โ
- Step 1 – Take 1000-664
- Step 2 โ Subtract 6 from 9 = 3
- Step 3 โ Subtract 6 from 9 = 3
- Step 4 โ Subtract 4 from 10 = 6
The answer is 336.

Multiplying any number 5 times
There will be 2 different tricks for even and odd numbers, respectively.
When multiplying an even number by 5 โ
Like 5 x 4 =
- Step 1: Half the number which has to be multiplied by 5, i.e. 4 becomes 2
- Step 2: Add a 0 at the end for the answer. Thus, 20
5 x 4 = 20
When multiplying an odd number by 5 โ
Like 5 x 3 =
- Step 1: Subtract 1 from the number which has to be multiplied by 5, i.e. 3 becomes 2
- Step 2: Now cut the number 2 in half, which becomes 1. 1 Will be the first digit and use 5 as the last digit in all cases. Thus, the answer is 15.
- 5 x 3 = 15
Finding the Percentage
You might find it challenging to calculate the percentage of a number, but thinking about it in the correct terms makes it much easier to grasp. For example, to find out what 5% of 236 is, use the following formula:
- Step 1: Put the decimal point over by one place. Therefore, 236 will become 23.6.
- Step 2: Now, halve 23.6, which is 11.8. This is the answer.

Complex Multiplication
When multiplying two large numbers, if one of them is an even number, divide it in half and then double it. This method will quickly solve the problem. Consider the following:
20 x 140
Step 1: Divide the number 20 by 2, which equals 10. Double 140, which equals 280. Then multiply your two answers together.
10 x 280 = 2800
The answer to 20 x 120 is 2,800.
Practising these quick math tricks can help anyone improve their math skills and become more confident in their mathematical knowledgeโthus, less afraid to work with numbers in the future.
