Multiplication Help <3

Here is some help for people who are tricked by multiplication.

1x

For 1x everything is like the following:

2x1=2

So the other factor that is not 1 is the answer.

2x

For 2x everything is doubled.

For example, 

4x2=8

Basically, you can just add 4+4!! Like 9x2 will be 18.

3x

Here is a song to remember:

3,6,9,

12,15,18,

21,24,27,

30

3x1 is 3, while 6x2 is 12, and so on.

4x

4 times is tricky. To remember, I count by twos: 2,4,6,8,

But I say every other one quickly.

For example,

2,4, 6, 8, 10, 12

Like that.

5x

You can just count by 5.

5, 10, 15, 20

It is easy because each number will end with 5 or 0.

6x

6x always stumps me.

The only way I got it was by memorizing. Here is a table:

6x1 6
6x2 12
6x3 18
6x4 24
6x5 30
6x6 36
6x7 42
6x8 48
6x9 54
6x10 60

7x

Same thing.

Here is another table:

7x1 7
7x2 14
7x3 21
7x4 28
7x5 35
7x6 42
7x7 49
7x8 56
7x9 63
7x10 70

8x

Same.

8x1 8
8x2 16
8x3 24
8x4 32
8x5 40
8x6 48
8x7 56
8x8 64
8x9 72
8x10 80

9x

9x is simple.

Put your hands out all fingers.

Then if you are doing 9x3, put down your third finger. On the left side of the third finger, there are 2 fingers up. Those 2 are the tens place; 20. On the right side of the third finger, there are 7 fingers up. Those 7 are the ones place; 7. 20+7=27

10x

10x is basically 1x but add a zero at the end.

For example:

2x10=20

7x10=70

and so on...

 

 

 

Hope this helps!
