Whole numbers are either odd or even.

Our 2 tree dwellers will help explain.

Bring on the bananas.

If we share an even number of bananas between our 2 swingers.

They'll have the same number of bananas each.

Everyone's happy.

Even numbers can always be split equally between 2.

And always end in a 0, 2, 4, 6 or 8.

But if we take this bunch of odd bananas.

Our furry friend has 1 less and is going ape!

That's because the number of bananas was odd.

Odd numbers always end in 1, 3, 5, 7 or 9.

And splitting these bananas is a lot less appealing.
