Mathematics Corner :)

**Ameeratul Layl** · 12-08-2005

This is like any other educational corner.
Only, this one will contain lots and lots of numbers

compared to the rest

Well, my dear brothers and sisters, do TRY to help each other as we are ordained to do so.

I also hope that those who do not enjoy mathematics will soon come to love it.Its a very challenging subject but it is indeed great fun!!!!:coolsis:

Allah ma3ak

Hey.

**Yanal** · 12-26-2008

Ahh Grandpa Woody, it was a joke , I think.

**chacha_jalebi** · 12-26-2008

2y x 5y = ?

go on yanal

**Yanal** · 12-26-2008

Well the answer is ....10yy.
Next question: What is c+h+a+c+h+a=

Here you go nature boy:

Find all prime numbers p if:
p + 28 = prime
p + 56 = prime

Nobody?

**Cabdullahi** · 12-27-2008

the question seems unclear,do we have to find out what p is? but then you say find all prime numbers that would fit in the equation

well the first one

19 + 28 = 47 which is a prime number ? is that how it is im not sure

the second equation
11 + 56 = 67 which is a prime number

**Cabdullahi** · 12-27-2008

ohhh i think you want us to find all the possibilities?? is that correct brother wtp?

**Güven** · 12-27-2008

Ive never seen such a question before , im sorry

You have to find every prime number that fits both equations.
19 + 28 = 47
however
19 + 56 is 75 which is not prime.
so p is not 19.

And you mustn't solve it by trying.

**Cabdullahi** · 12-27-2008

3 + 28 = 31

3 + 56 = 59

**Cabdullahi** · 12-27-2008

61 + 28 = 89

61 + 56 = 117

???

Nope, 117 = 39 × 3

Yep, but that was a guess.
Try figuring it out in a mathematical way.

I believe the question needs some parameters, otherwise there will be infinite possibilities. No matter what the largest one is, we can never rule out that there is a larger possibility.

Nope. 3 is the only solution.
