We have listed 13 interesting and easy math tricks to improve problem-solving abilities. These problem-solving tricks are will be handy for your kids and definitely improve accuracy as well as the speed at which they solve math problems. It is a great tool for timed mental math calculations as well.
#13. Quick Addition of 2-digit numbers
With this easy mathematics trick, you can calculate the sum of two digit numbers very fast and gain a better understanding of place values and decomposing.
For example: If you have to find the sum of 56 and 62. You will break the numbers into ten’s and one’s place mentally (56 becomes 50 & 6) and (62 becomes 60 & 2). Now, you will add the tens place first (50 + 60) = 110. Then, you will add the one’s place (6 +2) =8. Now you just need to add the two answers to get the total (110 + 8) =118.
#14. Addition by Rounding off
In this maths tricks for kids for addition, you will modify the numbers by rounding them off so they become much easier to work with. It also increases reasoning in math.
For example. If you have to add 397 and 95. You will take the larger number and round it off to the nearest higher number. So for 397, you will add 3 to make it 400. Now, you will subtract the same value 3 from the second number 95, which becomes 92. Now you will just add (400 + 92) = 492, which is a much simpler calculation. And, the correct answer is indeed 492.
#15. Subtraction by Rounding off
This is similar to the above described “Addition by Rounding off” trick except that you will be performing subtraction instead. For the subtraction trick, you will round off the larger number to the nearest smaller number instead.
For example: If the question is find the difference of 494 and 97. You will take the larger number and round it off to the nearest lower number. So, 494 will be rounded off to 400, which is done by subtracting 94 from 494 (494 -94= 400). Now, you will subtract the same digit i.e. 94 from the second number (97 – 94 = 3). Now you will subtract these two to get the final answer (400 -3) = 397, which is the correct answer for (494 – 97).

#16. Subtraction involving numbers with the power of 10
This simple math trick can be used to subtract any 3 digit number from 1000. You just need to subtract the digits of the number from 9, except the last digit which you need to subtract for 10.
For example: If you need to subtract 837 from 1000, you will subtract the first digit 8 and second digit 3 from 9, (9-8=1), and (9-3=7). Now, you will subtract the last digit 7 from 10 (10-7=3). Now you will just put the number together. So, the answer is 173.
You can also use this method to subtract any 4 digit number from 10,000 or 5 digit number from 100,000 and so on.
#17. Using Fingers for Multiplication of 9

The number of fingers to the right side of the folded finder will be the second digit number. So the answer is 36.
#18. Quick Multiplication by Decomposing
This easy maths trick can be used to perform multiplications quickly by make the equation easier to work with. This method also encourages logical thinking. In this method, you will just break the numbers into smaller components as needed.
For example: If you have to multiply (13 x 16). You can break down the numbers. So, 16 becomes (2 x 8). Now, you can also write the equation as (2 x 8 x 13). You can first multiply (13 x 8) = 104, and the equation becomes (2 x 104), which is much simpler and the answer is 208, which is the answer for (13 x 16).
#19. Quick Multiplication by 9
This simple maths tricks for kids can be employed to multiply any number by 9. This trick is time saving and so simple, and your child just needs addition skills. In this method, you just need to add 0 to the number that is to be multiplied by 9 and then subtract the original number from it.

Now, add the two digits together (3+4=7) and put this sum in the blank space (374), which will be the answer, (34 x 11) is 374.
If incase the sum is greater than 9, you need to put 2nd digit in the space and add 1 to the number left of the space.
#21. Quick Multiplication by 5
This is an easy math trick for kids that can be used to multiply any numbers by 5. The method differs for even and odd numbers.
For even numbers: Divide the even number to be multiplied by 5 by 2 and then simply add 0 in the end. For example: If you have to multiply (5 x 12). Divide 12 by 2 which gives 6. Now, add 0 at the end. So, the answer is 60, which is the correct answer for (5 x 12).
For odd numbers: Subtract 1 from the odd number to be multiplied by 5 to make it an even number. Now, divide this number by 2. Then, simply add 5 in the end to get the answer. For example: If you have to multiply (5 x 13). First subtract 1 from 13, which gives 12. Then, divide 12 by 2 which gives 6. Now, add 5 at the end. So, the answer is 65, which is the correct answer for (5 x 13).
#22. Quick Multiplication by 15
Using this amazing maths trick, you can easily multiply any number with 15. It is super easy. In this method, you just have to add 0 at the end of the number that is to be multiplied by 15, then divide this number by 2 and add both the numbers together to get the answer.
For example: If you have to multiply 83 by 15. You will simply add zero to 83, which then becomes 830. Now you will divide this number by 2, so (830 / 2 = 415). Now, add the two numbers together (830 + 415) = 1254, which is the answer for (83 x 15).
#23. Quick Multiplication by 25
This maths trick is perfect for multiplying any number with 25. In this method, you just need to divide the number to be multiplied by 4 and then add two 0’s at the end.
For example: If you have to multiply 16 x 25. You will divide 16 by 4 (16 / 4) = 4. Now simply, add two 0’s at the end. So, the answer is 400.
If the number cannot be divided by 4, no problem. There is a simple solution to this. You will still divide the number by 4, but pay attention to the remainder. If the remainder is 1, add 25 to the answer or if it is 2, add 50 to the answer, and so on in increments of 25.
For example: If you have to multiply (27 x 25), you will divide 27 by 4, the answer is 6 with 3 as the remainder. So, the answer will be (600 + 75) = 675, which is the correct answer for (27 x 25).
