Subject: Math trick
Math trick - this is cool! You've got to try this... kind of intriguing.
1. Key in the first 3 digit of your phone number into the calculator.
2. Multiply by 80.
3. Add 1.
4. Multiply by 250.
5. Plus last 4 digit of your phone number.
6. Plus last 4 digit of your phone number again.
7. Minus 250.
8. Divide by 2 at last.
Is this your handy phone number???

Anyone know why it works? It's basically like adding 1 then multiplying by 1 then subtracting 1 from the same number...
Example 100 9999
100x80 = 8000
8000+1 = 8001
8001x250 = 2000250 - interesting, this is 7 digits long.
2000250+(2x9999)=2000250+19998=2020248
2020248-250=2019998... hmm... if we didnt add 1 in step 2 we wouldnt need to do this.
2019998/2=1009999
Ok let's skip steps 2 and 7, same numbers
100x80 = 8000
8000x250 = 200000 ... there's our 7 digits without the extra 250 in there
lets divide by 2 here and only add the last 4 digits once
1000000+9999=1009999
Wow, same number
Ok let's change the 80 to 40 and only add the last 4 once
100x40 = 4000
4000x250 = 1000000
1000000+9999=1009999
We can combine the x40 and x250 into x10000
100x10000+9999=1009999
Ok, here try this now
1. Multiply the first 3 digits of your phone number by 10000
2. Add the last 4 digits of your phone number
3. Eureka! You've found your phone number!

Did you try my modified version at the end of my post? If that doesn't work then I think you need a new calculator... or need to memorize your phone number :P
