Maths - odd or even
20 Jun 2014
Are these numbers odd or even?
I must remember to look look at the digit in the
unit colomn.
I know that 22 is the even number after 20.
I am so glad I have my 10 fingers to help me work out the answer.
If I add an even number to an odd number, the answer will be odd.
