Take for instance this. Pick a number, add 2, multiply by 4, subtract 8, divide by 4. You get the number you started with
Take any number. Say X
Add 2 to it, v get X + 2. Multiply by 4. v get (X+2)*4. the result is 4X+8. now subtract 8. v get 4X. then divide by 4. v get X.
What happens is that, in the above example v perform 2 actions first and the rest 2 actions are performed to nullify the effect of the first 2 actions. First v add 2 and then multiply by 4. It is same as multiply the original number by 4 and adding 8. At the end v subtract 8 to cancel the effect.
The same can be noted with the above mention cell number trick.
The steps can be easily understood
1.Take first 6 numbers of any cell number
2.Multiply with 80
3.Add 1 to it
4.Multiply with 250
5.Add the last 4 digits of ur number
6.Again add the last 4 digits ur number
7.Subtract 250
8.Divide by two
The answer is always ur cell number.
Here, law of association begins in the step 3 and ends in step 7. Say the result of step 2 is X. performing step 3, v get X+1. Performing step 4, v get (X+1)*250, that is (X*250+250). Assuming “y” is to be the last 4 digits. Performing step 5 and 6, v get (x*250+250+2y). now performing step 7, v get (x*250+2y). It is like the step 3 and 7 are nullifying each other.
So, v can safely remove both, step 3 and 7. So v get
1.Take first 6 numbers of any cell number
2.Multiply with 80
3.Multiply with 250
4.Add the last 4 digits of ur number
5.Again add the last 4 digits ur number
6.Divide by two
The result will still be the same.
Now combine step 1 and 2, instead of multiplying with 80 and then by 250, v can directly multiply by 20000.
The net effect is that the six digit number is multiplied by 2 and then moved to the right by 4 digits.
Now v add twice the last 4 digits. Why twice the last 4 digits? It can be only once also, if the 6 digits are multiplied with a net effect of 10000. But it is not so. It is multiplied by twice of 10000. This twice is again removed altogether in step 6.
That is u can safely remove the last step 6. U will get
1.Take first 6 numbers of any cell number
2.Multiply with 10000
3.Add the last 4 digits of ur number
In these three steps, whatever 10 digit number u take, u get the same number. This is the basis of the trick.
Hey that’s a cool trick u got there.
Do anyone know the basis of such a trick.
It is very simple. It is law of Association.
I will illustrate it.
Take for instance this. Pick a number, add 2, multiply by 4, subtract 8, divide by 4. You get the number you started with

It is one of the oldest trick in the oldest book.
