Mental Math and Multplication

By Sam Roxas


Most kids do not really see math as a problem during their addition and subtraction classes. But the instant multiplication hits, they'd start their fiery hate for mathematics.

But this can be evaded if they discover mental math as early as is possible.

Mental math lessons work well with small children because their brains are extremely able and capable to soak up as much new info as possible. The best time for mental math lessons would be from age 1 to 8.

But if your kid is older than eight years old , you don't really have to worry. All hope isn't yet lost- they can still learn and experience the advantage of mental math.

Most youngsters need to just enjoy and have a great time. They don't really need to think of "heavy ' things. They would like to do things quick and simple.

Now, when it comes to mental math and multiplication, there are actually tons of techniques that your children could learn to multiply numbers without a pen and paper. They would surely enjoy these tricks.

For the following mental math multiplication method, it is important to note that your children must have memorized the multiplication table for one to ten to be well placed to perform these mental math tricks.

If your kids are not familiar yet with the multiplication table, you can actually teach them and help them to try this through abacus math. It is a fun, easy and effective way to learn the multiplication table.

The 1st trick is for multiplying a two-digit numeral by an one-digit numeral. We'll do this with the left-to-right technique.

Now, I know that this is something that can come as a surprise to you and your kids. We are all used to performing mathematical equations from the right to the left. But this trick will show you that multiplying a 2-by-1 equation is far easier if done from left to right.

42 x 7 =?

First, multiply 40 x 7 = 280.

Next, multiply 2 x 7= 14.

Finally, add the 2 products: 280 + 14 = 294.

And there you have it! 42 x 7 = 294.

Here's a better and clearer illustration:

42 (40 +2)

X 7

-----------

40 x 7= 280

2 x 7 = + 14

------------

294



This mental maths technique of multiplying a single digit by a double-digit number is evidence that multiplication isn't actually that tricky. Mental math strategies actually show that maths can be fun and easy with the employment of different tricks and methodologies.

Multiplication is one of many ideas of maths that's considered extraordinarily hard by children. Showing them these tricks will make them see the notion that "math is hard" isn't true at all.
