Here is a collection of 10 Math tricks you can learn to trick your friends and make yourself fall in love with the subject of numbers.

Trick 1: The Answer for Anything Would be 37

• Step 1: Choose a three-digit number with the same digits. Let’s go with 333.
• Step 2: Add the digits together. So, 3 + 3 + 3 = 9.
• Step 3: Divide the original number by this sum. So, 333 / 9 = 37.
• Step 4: This works every single time.

Trick 2: Amazing magic of number 1089!

• Step 1: Choose any number, like 537.
• Step 2: Now the digits require to be ordered in descending order, 753. This is your 1st number.
• Step 3: Replace or rearrange the same digits in the ascending order, 357. This is your 2nd number.
• Step 4: Subtract the 2nd from the 1st, which will give us the answer, 753 – 357 = 396.
• Step 5: Now change the order of digits of the answer to getting the number, 693.
• Step 6: Let’s add both the numbers, 396 + 693 = 1089!

Trick 3: And the answer will always be 15

Yet another trick that makes you turn to the number 15 no matter what number you choose.

• Step 1: Think of a number, such as 279.
• Step 2: Multiply it by 3. So, 279 x 3 = 837.
• Step 3: Now add 45 to the answer. So, 837 + 45 = 882.
• Step 4: Multiply the answer by 2. So, 882 x 2 = 1764.
• Step 5: Divide this answer by 6. This will give you 1764 / 6 = 294.
• Step 6: Subtract your original number from this answer.
• Step 7: That makes it 294 – 279 = 15. Surprising, right?

Trick 4: Guess the age of your friend

• Step 1: Take the year your was born, let’s say 1985
• Step 2: Add 12 to the year.(1985 + 12 =1997)
• Step 3: Divide by 2.(1997/2 = 998.5)
• Step 4: Subtract 1000 from the answer in the step 3.(1000 – 998.5=2.5)
• Step 5: Multiply by the result with 10.(2.5 x 10 =25)
• Step 6: Add 9 to the result in step 5.(25+9=34). The result is the age of your Friend

Trick 5: Adding 2-Digit Numbers at Extremely Fast Lightning Speed

By understanding the basic principles of tens & units places, you can add two-digit numbers literally in a snap.

• Step 1: Take 57 + 79.
• Step 2: Split the 2nd number into tens & units, making it 79 = 70 + 9.
• Step 3: End up the tens addition, which is 57 + 70 = 137.
• Step 4: Now must add the left units place digit, which is 137 + 9 = 146. That’s it; you’re done.

Trick 6: Predict the Number

• Step 1: Subtract one from the upper number. 22 – 1 = 21
• Step 2: Multiply it with three. (21 x 3 = 63)
• Step 3: Add 12 to this number. (63 + 12 = 75)
• Step 4: Divide it with three. (75 / 3 = 25)
• Step 5: Now add 5 to the above number. (25 + 5 – 30)
• Step 6: Finally, ask your, friend, to subtract the original number from the above sum.
• Step 7: The answer will always be 8. (30 – 22 = 8)

Trick 7: Choose any number, your end product will only be 2!

• Step 1: Ask your friend to think of a number, let’s say 16
• Step 2: Multiply it with three. (16 x 3 = 48)
• Step 3: Add 6 to this number. (48 + 6 = 54)
• Step 4: Divide it with three. (54 / 3 = 18)
• Step 5: Subtract the number chosen in step 1 with step 4 (18–16= 2) The answer will always be 2.

Trick 8: Shoe Math Tricks

• Step 1: Multiply show size by 5, let’s say 5 is the show number. (5 x 5 =25)
• Step 2: Add 50 to the result obtained in step 1. (25+50 =75)
• Step 3: Multiply the number obtained in step 2 by 20. (75 x 20= 1500)
• Step 4: Now ADD 1019.(1500 + 1019 = 2519)
• Step 5: Subtract the year you were born with the above number. (2519 – 1985 =534)
• Step 6: Finally, the first digit of the number reflects the show size(534) and the last 2 digits show the age (534)

Trick 9: 1, 2, 4, 5, 7, 8 Math Trick
