More Eggs Eggs Eggs.... and no '7's

However, I would argue that decimal and fraction results are a more advanced form of division. When I was a kid at school just after we learned our times tables, we learned that a number was either divisible by another number or it was not. So for example, 10 is divisible by 2 but not by 3. Then later on we learned the messy truth. So if you were coming from the most basic background, it should be more acceptable to say that 101 is not divisible by any number other than itself and 1, than to say that it's divisible by anything if you're happy to accept a fraction, decimal or a remainder result. So should the assumption be based on the more basic definition or the more complicated one?

But thats misleading as evenly can be understood to be it can only divided by an equal number giving an equal half giving equal parts with answers including fractions.

Whats funny about my fear anxieties with maths is that in science at school my teacher pushed for me to go on to year 12 based on my understanding of maths and science

Anything can be misunderstood. You have to assume a basic level of understanding and then cater for the exceptions when they happen, otherwise we'd all talk like lawyers.

Whenever we say X is divisible by Y. By default we are talking about integers and zero remainder.

If you use non-integers, fraction or decimal then it would be pointless becasue everything would be divisible by something else anyway.

Greg want to apologize for hijacking the thread

lawyers are generally great mathematicians they get the money either way and they normally work 101

Wheelin, there's more eggs where they came from, I'll just see what I can find next to annoy.

Wongo's quote: 'everything would be divisible by something else anyway'.

Now that's a big statement..... what about pi?

yeah - it would just be another infinite number wouldnt it?

**Greg Ward** · 21st January 2008, 04:09 PM

It's OK I know the answer.....

Wongo states pi is divisible by pi and Wheeling just cuts the pie into sections and sells them with the eggs

You can't use Pi in a calculation so you have to use an approximate value, and the approximate value you choose is also potentially divisible by any other rational number, right? So Pi is not divisible but 3.14159 is.

just don't have a circile 101 circumfance

Hey I didn't say Pi is divisible by Pi. I said Pi divided by pi is 1.

**Greg Ward** · 21st January 2008, 04:17 PM

You could use Pi in a calculation:

'Find the relationship between two circle diameters with radii of 1 and 2'.

D = 2 x pi x r

D1/D2 = 2 x pi x 1/ 2 x pi x 2 = 1/2

No estimate needed......

But your using Pi as a variable/symbol not a actual number. Gee I love aglebra.
