A number is said to be even if and only if it is divisible by 2; otherwise, it’s said to be odd. Another way to know whether a number is even or odd, simply look at its last digit. If a number ends in 0, 2, 4, 6, or 8, then it’s even, but if it ends in 1, 3, 5, 7, or 9, then it’s odd. For instance, looking at the numbers 125 and 236, we can see that, since 5 is the last digit of 125, it’s odd, while 236 ends in 6, which is divisible by 2, so it’s even. Learn how to identify a number whether it is an even or odd by helping Odd Autumn and Even Steven, the two intrepid friends who are on a quest to the Splitcypress Forest to find a Puffstritch, divide their haul or food evenly.
