Birthday Equation?

Does anybody remeber that equation to get your birthday? I remeber it having to ask you several questions having to do with numbers and the answer will tell you how old you are, or when you were born..

Why you ask? I have to make a game in my programming class which is worth 10% of my mark so im just going to choose something simple that will get me the mark i need.

Google is your friend : )

heres a few i found.

1. multiply your age by 7
2. now multiply that product by 1443
3. your age appears 3 times repeating (EDIT forgot)

1. Pick a number, any number
2. Multiply this number by 2
3. Add 5
4. Multiply it by 50
5. If you have already had your birthday this year add 1753. If you haven't, add 1752. (each year these numbers increase by 1. In 2004, you'd add 1754 if you already had your bithday and 1753 if you haven't)
6. Subtract the 4 digit year that you were born.

don't if that was completely what you were looking for but its a start at least.

Was my equation not good enough for you?

Start with number X.

Multiply by 2.

Raise to the second power.

Divide by four.

Take the square root of that number.

You can edit this formula, so long as you start and end with X, to be as long and complex as you desire.

(Example with X:)

X-Start #
2X-2*Start #
4*(X^2)-(2*Start #)^2
X^2-Above divided by four
X-Square root of above.

Thanks, exactly what im looking for, but the only one that worked was Grinding's. However, i had to enter my birthday (which if i programmed it, i could just easily record that 4 digit number of the year you were born, and people would think i just recorded that number and subtracted it with the current year)

I've decided that im gonna make the exact same game as this:

But keep comming with the answers, a mini game wouldnt hurt my mark :)

such a silly game. i mean they should've tried to at least make a mini game in which the trick would work twice without the person realizing it. :(
the only possible numbers are all taken by the same symbol. meh.

There are more than 1 possible symbol =/

o rly? my mistake then. cause i did a few tries and they all ended up being the same symbol. oops.

Wait a sec, your right nvm :X

They change the symbols every time you press try again :X

:roll:
Ya it's cause i never pressed the try again button. i just picked 2-3 numbers and checked them on the same symbol screen.
there's a certain set of numbers which are always the answers. so their symbol is the same except when you press try again, it changes to a different symbol to trick you.

Yeah, but instead of like 3 sets of symbols, ill have 7, and i'll program it that it'll be a random set everytime the person clicks "Try Again" :)

Is a silly game indeed. I ran it and at the begginig I was like woah, nice! ... then did it a couple of times and figures how it was done.

For people that think that this is real, you guys should do some critical thinking :P . Try figuring it out by yourself. Make your braincells work!

If people want, I can give the answer... but I'm pretty sure you will all get it.

PS: there is some logic to it...

i don't know how they do this but heres my guess, your so focused into making something appear that you do make it appear, like an imaginary friend. =P

my logic wins!

Heres a program I wrote for you, its a cass cheat lol
its in Python

Code: Select all

x = int(raw_input("Your age here: "))
y = int(x * 7)
print "Your Age by 3 = ", int(y * 1443)


I added int() to the numericals so it would round, I ran the program and it didnt and did the number forever lol, but when u make them integer instead of float it will round ^_^

Yeah taking a 2 digit number then adding the 2 digits, then taking the original number and subtracting it by the sum of the 2 digits will always give you a multiple of 9.

so 0,9,18,27,36,45,etc. etc. should all be the same symbol

I figured it out

5you chose 56 5+6 = 11 56-11
Now the chart makes same symbol for each 9 differnce
and then when u go to try again it makes it a different symbol ,so even if u pick a different number, the made the symbol same for each number than relate to the simple equation, i can write a program like that lol
