2(2)=4+2=8+2=10+2=12
3(3)=9+3=12+3=15+3=18
4(4)=16+4=20+4=24+4=28
5(5)=25+5=30+5=35+5=40
12(12)=144+12=156+12=168
17(17)= 289+17=306+17=323
The same kind of sequences can be applied to all of multiplication
But i am confused about division?????
Is just like subtraction like multplication is just addition??
Stupid question but i am just that way:(

Can you show me?how it works

Addition and Multiplication are both defined as we know them:
1+1=2
10+10=20
2•2=4
and so on.
Subtraction and Division is more like asking a question. The question is for subtraction:
5-3=? means What number plus 3 equals 5.
The question for division:
5/3=? means what number times 3 equals 5.
Even though there is a relation between multiplication and addition (this is called the distributive property), there isn't one between subtraction and division, because division is defined by multiplication. Therefore you would have to build a chain that connects subtraction to addition to multiplication to division. Something that doesn't really exist.

In a word 'yes'
Multiplication is repeated addition
3 x 7 = "What is 3 lots of 7?" = 7 + 7 + 7 (= 21)
Similarly division is repeated subtraction
45 ÷ 9 = "how many times can you subtract 9 from 45?"
= 45 - 9 - 9 - 9 - 9 - 9
So you can do it exactly 5 times (no remainder)

12/4 = 3. Now with repeated subtraction:
12 -4 = 8 (1x)
8 - 4 = 4 (2x)
4 - 4 = 0 (3x). Ready and no remainder.
By the way: 4+2=8+2=10+2=12 is nonsense !!
However I understand what you mean.

Hi. Division is more like cutting. Divide an apple in two. That is different from subtracting.

In effect.
5 times 10 is 5+5+5+5.........
So you can consider 50 / 10 to be
50 -10 -10 -10 -10 ........
