It's easily adaptable. Not that difficult to work out :P
People in the UK have 6 digit phone numbers, instead of multiplying by 80 in the first step. Multiply by 8.
If you have an 8 digit number, multiply by 800.

Re: todays math fun is brought to you by the letters W T and F
Do you have a six digit telephone number, if so you're a geptard.
Example 123456
123*8 = 984
984 + 1 = 985
985*250 = 246250
246250 + 456 = 246706
246706 = 345 = 247162
247162 - 250 = 246912
246912\2 = 123456

Meh, you're from London. There are too many people there for any sense.
Also chavs breed quicker than proper people, London needs the extra 90 million phone numbers, just incase :unsure:

The first step is multiplying by 8 (2X2X2); cancel out step 7 by removing one of the twos.
Step 5 is also cancelled because you've gotten rid of the divisor of two at the end so you must not add the last three digits a second time.
This means that step seven is gone, step 5 is gone and you're multiplying by 4 in the first instance.
We now have
1 Multiply first 3 digits by 4
2 Add 1
3 Multiply by 250
4 Add last three digits
5 Subtract 250
Still works, right?
Steps 2 and 5 cancel themselves out since adding one before multiplying by 250 has the effect of adding 250 to the figure.
We now have
1 Multiply first 3 numbers by 4
2 Multiply by 250
3 Add last 3 digits
Since 4*250= 1000 we may as well simplify further and get rid of step 2 by making step one the first 3 numbers*1000
Now we're left with
1 Multiply the first 3 numbers by 1000
2 Add last 3 digits.
The above is moving the 3 digit number 3 decimal places to the left and slotting in the last 3 digits.
=> It works for everyone.
Note: It's the same principle for 7 digit numbers, it just cancels down to multiplying by 10000 rather than 1000 in it's simplest form.
