Math Tricks

Math tricks are often done out of boredom. They tend to release anger and depression. They seem to have the power to make us wonder. But others consider math tricks as helpful methods that can improve their math skills.

Amongst the most popular math tricks is the 10-rule. This can allow you to easily get the product of any number multiplied by 10. Just add 0 to the number and you get the product of the number multiplied by 10.

 

To easily multiply any 2-digit number by 11, you should use the 11-rule. For instance, the 2-digit number to be multiplied by 11 is 54. First, separate the two digits. Afterwards, add 5 and 4 together (5+4=9). Put the sum between the 2 numbers, and you’ll get 594. So 11 multiplied by 54 is equal to 594.

 

 

But if the sum is greater than 9, you only put the "ones" digit in between the numbers and carry over the "tens" digit – example: 11 x 57 ... 5__7 ... 5+7=12 ... put 2 between the numbers and add 1 from the 12 to 5 in order to get 6 for a result of 627 ... 11 x 57 = 627

These rules were made from patterns and generalizations. For more, it’s just a matter of going to MathComplete.Com since this site is always updated with the newest math tricks available. This means you can regularly check this site for updated math tricks.
