## How to simplify times tables practice: Times tables principles and secrets

The first secret or principle to help children understand times tables is to learn from skip counting (by skipping a regular interval of numbers). This allows children to take a fast and flexible hand that effectively increases their multiplication skills. That why you’ll find here both Times tables practice quiz and Multiplication trainer online.

In what follows, we will discover little principles set up to review and easily understand each times tables.

Let’s start with x 0 times tables. Any number multiplied by 0 gives 0.

### x 1 times tables principle

For the multiplication by 1, it is not necessary to learn a particular technique, because for x 1 times tables there is a simple principle; “any number multiplied by 1 is the number itself”.

Example: 1 x 1 = 1; 2 x 1 = 2; … 12 x 1 = 12

### x 2 times tables principle

Multiplication by 2 is relatively simple; just know count even numbers or skip counting by twos.
By simply knowing the duplicate numbers, it also works very well.

Example: 1 x 2 = 1 + 1 = 2; 2 x 2 = 2 + 2 = 4; … 12 x 2 = 12 + 12 = 24

### x 3 times tables principle

To easily learn the multiplication by 3, the child will know skip counting by threes; it is a fast and safe way to understand x 3 times tables.
0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33 and 36

We can also use a simple tip which consist to add the number 3 times:
3 x 3 = (3 x 2) + 3 = 9. Multiply by 3 means that we add the double of the number + the number.

### x 4 times tables principle

The x 4 times tables has a very profitable trick for kids who are fast with additions; multiply a number by 4 is equivalent to add his double twice.

Example: 6 x 4 = (6 x 2) + (6 x 2) = 12 + 12 = 24; 8 x 2 = 16 + 16 = 32

It’s also easy to know skip counting by fours: 0, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, and 48.

### x 5 times tables principle

For the x 5 times tables, you will quickly get familiar with switching between 0 and 5. An even number multiplied by 5 have a result that ends with 0; for the odd number is 5.

Thus one gets the skip counting by fives: 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, and 60.

### x 6 times tables principle

Multiply a number by 6 means to find the double of that number multiplied by 3.
Example: 7 x 6 = 7 x 3 x 2 = 21 + 21 = 42; 4 x 6 = 12 + 12 = 24

Moreover skip counting by sixes gives: 0, 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66 and 72

### x 7 times tables principle

After learning the multiplication tables up to 6, the child also masters x 7 times tables up to 6, rest now numbers 7 to 12. It is not at all hard to memorize.

Using skip counting by sevens, we have the products: 0, 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77 and 84.

### x 8 times tables principle

For the x 8 times tables, the multiplications are already mastered up to 7; there are only remained numbers 8 to 12, which are relatively easy to memorize. Another trick is to do a sum of the double of that number multiplied by 4 (in this case, one must know x 4 times tables).

Example: 6 x 8 = 6 x 4 x 2 = 24 + 24 = 48; 3 x 8 = 12 + 12 = 24

### x 9 times tables principle

Multiplying by 9 is one of the easiest times tables to remember. Multiply a number by 9 means to add a zero behind that number and subtract its own value.

Example: 7 x 9 = 70 – 7 = 63; 4 x 9 = 40 – 4 = 36

### x 10 times tables principle

Multiplying by 10 is the simplest after multiplication by 0 and 1. Multiply a number by 10 means to add a 0 to the number just at the location of the units; which adds an extra digit.

Example: 5 x 10 = 50; 3 x 10 = 30

### x 11 times tables principle

When multiplying numbers from 1 to 9 by 11, we’ll just write that number twice by adding an extra digit.

Example: 6 x 11 = 66; 8 x 11 = 88

For multiplication by 11 with the numbers 10, 11 and 12, it is easy to remember the products 110, 121 and 132.

### x 12 times tables principle

Here there’s also x 12 Times tables practice quiz. To multiply a number by 12, decompose the multiplication sentence as follows: n x 12 = (n x 10) + (n × 2).

That means to multiply that number by 10 and add the product with its double.

Example: 7 x 12 = 70 + 14 = 84; 11 x 12 = 110 + 22 = 132 … You are there, it’s easy!
