Multiplying by 11

Multiplying by 11 is easier when adjusting the rule for multiplying by 9. Just think of11 as (10+1) So 436 × 11 = 4360 + 436 = 4796…that’s the simpler way of explaining why the digits add up to each other like youwrote: 4360 + 436 —– 4796

Addition Tricks – Addition from Left To Right

When you learned how to do math in school, you probably learned how to do it from right to left.  One of the secrets to doing fast math tricks in your head is to learn how to solve mathematical problems from left to right. Actually, learning this mathtricks method is not very difficult.  In fact, your brain is already hard-wired for solving math problems from left to right; you have spent years reading left to right, correct?  Well, then your brain is trained to think from left to right – so lets try it with some simple addition problems! Addition Example 1 45 + 38 This is a very easy problem, and it is even easier if you solve it from left to right.  First, break down the number 38 into it’s tens and ones: 30 + 8 Now add the numbers in this fashion: 45 + 30 75 + 8 = 83 So the full breakdown of theproblem looks like this: 45 + 38 = 45 + (30 + 8) Once you have the problem in this format, it is much easier to solve. Addition Example 2 384 + 467 Once again, to solve this pr

Square any two digits number that ends with 5

Square any two digits number that ends with 5 Calculating the square of a number below 100 is extremely simple. If you wantto find the square of 25 for example, you simply have to take the first digit (2), multiply it for the next highernumber (3), and then add 25 to the result. For example 1). 25*25 now, (2*3)25=625 2). 75*75 now, (7*8)25=5625
