This is a post by my kid, His first post! The rest of the text below is his attempt at explaining odd and even numbers.

Odd and Even numbers

200=100+100

100=50+50

50=25+25

25=Cannot be broken down into two equal parts.

Let me explain. You see the other numbers I have put? Those ones can be broken into two equal parts, that makes the number which was broken into two equal parts an even number. The ones which cannot be broken down to two equal parts are odd numbers. So that means 25 is an odd number. You can do this method to figure out which is an even number and odd.

edit 15apr2022: Changed “by two equal parts” to “into two equal parts”.
