Mathematics is known as one of the core subjects in our education system. Its reason is that mathematics is helpful for us in our practical lives. Some essential benefits of learning mathematics are that it is good for our mind, it is helpful for us to tell time, it is helpful to solve financial problems, it is helpful to enhance problem-solving skills and math is also helpful for us to explore the world. Now, the problem is that there are some mathematical concepts that are harder to learn for us. Here, we will discuss some math magic tricks and questions that will blow your mind.
Math Magic Tricks and Questions in Tabular Form
1. Adding Large Numbers – Math Magic Tricks and Questions
To add smaller numbers is easy for us because we can easily add these smaller numbers in our mind but when we are asked to add larger numbers, we have to use a calculator or we have to add these numbers by following the manual process. With the help of a math trick, it is easy for you to add these larger numbers. Here, we will discuss the complete process to add larger numbers by using a math trick.
i. First of all, you will have to take two larger digits that you want to add. For example, we have to add 774 and 338.
ii. It is hard for us to connect 774 and 338. Therefore, before solving these numbers, we should try to round off these numbers. After rounding these numbers, we
get two new numbers 780 and 340.
get two new numbers 780 and 340.
iii. Now, it is easy for us to add these two numbers 780 and 340. After adding these two numbers, we get the answer 1120.
iv. After that, we have to get an idea about rounding off digits. 780 – 774 = 6 and 340 – 338 = 2.
v. Now, we have to add these two digits 6 and 2. After adding these digits, we get the answer 8.
vi. Now, we have to subtract 8 from 1120. 1120 – 8 = 1112.
vii. After adding 774 and 338 by using the calculator, we will also get the same answer 1112.

2. Subtract Any Large Number From 1,000
To subtract any smaller number from 1,000 is also easy for us but to subtract a larger number from 1,000 is difficult for the students. We can easily subtract any larger number from 1,000 by following this simple math trick.
i. First of all, we have to take a number. For example, we have to subtract 783 from 1,000.
ii. Secondly, you should take its first digit and subtract it from 9. 9 – 7 = 2
iii. Now, you should take its second digit and subtract it from 9. 9 – 8 = 1
iv. After that, you should take its last digit and subtract it from 10. 10 – 3 = 7
v. At last, you should combine these numbers as 217 and 217 is the required answer.
vi. If we subtract 783 from 1,000 by using a calculator, we will also get the same answer 217.
3. Five Times Multiplying Math Magic Trick
If we want to multiply 5 with any even number, it is easy for us to get its answer without using a calculator or by following the multiplication process with the help of a simple math magic trick.
i. First of all, we have to consider a number that we want to multiply by 5. For
example, we want to multiply 8 by 5.
example, we want to multiply 8 by 5.
ii. Secondly, we have to divide this number by 2. After dividing 8 by 2, we get the answer 4.
iii. After adding 0 at the end of this number, we get the required number. In this case, we get the answer 40.
iv. If we multiply 5 by 8 by using a calculator, we will also get the same answer 40. In a similar way, it is also possible for us to get the answer to the multiplication of an odd number with 5 by using a simple math magic trick. This magic trick is different from the above trick.
v. First of all, we will have to consider a number that we want to multiply by 5. For example, we want to multiply 7 by 5.
vi. Secondly, we should subtract 1 from this number. In this case, we will get another number 6.
vii. Thirdly, we should divide this number by 2 and we will get a new number 3.
viii. By adding 5 at the end of this number, you will get the required answer and that is 35.
ix. If we multiply 7 by 5 by using the calculator, we will also get the same answer 35.
4. Nine Times Multiplying Math Magic Tricks
Math magic tricks and questions are also helpful for us in getting the answer to multiplying any number with 9. This math magic trick is explained below;
i. First of all, we will have to consider a number that we want to multiply by 9. For example, we want to multiply 7 by 9.
ii. Secondly, we have to subtract 1 from this number and after subtracting 1 from 7, we get 6.
iii. 6 is the first digit of the answer. In order to get the second digit of the answer, we have to subtract 6 from 9. 9 – 6 = 3.
iv. Now, the required answer is 63.
v. If we multiply 9 by 7 by using a calculator, we will also get the same answer 63.
5. Math Magic Trick of Multiplying By 6
No doubt, almost all high school students have learned the table of 6 but most of the students don’t have noticed this math magic trick of multiplying by 6. If we multiply an even number with 6, the answer at the one’s place will be that number and the answer at the tens place will be half of that number. For example, if we multiply 6 by 8, we get the answer 48. The digit at one place is 8 which is the same digit and the digit at the tens place is 4 which is half of that digit.
6. Math Magic Trick of Answer 2
You can play a math magic trick with yourself or with your friends and in the end; you will notice that your answer will be 2. This math magic trick is explained below;
i. First of all, you will have to consider a random number. For example, we take a random number 5.
ii. Secondly, you will have to multiply this number by 3. After multiplying 5 by 3, you will get the answer 15.
iii. Thirdly, you should add 6 in the answer to step two. The new answer is 21.
iv. Fourthly, you should divide it by 3. After dividing 21 by 3, you will get the answer 7.
v. At last, you should subtract the answer of step four from your original number. 7-5 = 2.
7. Math Magic Trick of Same Three-Digit Numbers
You can also play this math magic trick with your friends. After playing this game, you will see that your answer will be 37 all the time. Its process is explained below;
i. First of all, you should consider a three-digit number that has the same digits. For example, we have considered 444.
ii. Secondly, you will have to add these digits. After adding these digits, we get the answer 12.
iii. Thirdly, you should divide the original number with the answer to the second step. After dividing 444 by 12, we get the answer 37.
8. Six Digits Become Three
You can also play this magic of six digits with your friends. After playing this magic trick, you and your friends will find that these six digits will become three. You can easily play this math trick by following these steps;
i. First of all, you should think three digits in your mind. For example, the required three digits number is 351. Write these three digits twice and you will get new the new number 351351.
ii. Secondly, you will have to divide it by 7. After dividing this number by 7, we get 50,193.
iii. Thirdly, you will have to divide it by 11. After dividing it by 11, you will get 4,563.
iv. Fourthly, you will have to divide it by 13. After dividing it by 13, you will get 351, and 351 is the digit that you considered the first time in your mind.
