What is the number 9?
The number 9 is an odd number that comes just after 8 and right before 10. It is not a prime number because it can be evenly divided by 3, in addition to 1 and itself. In American politics, William Henry Harrison was the 9th president of the United States. He served in 1841 but died just one month after taking office, making his term the shortest in U.S. history. In math, 9 is a square number because it equals 3 times 3. In sports, a baseball team has 9 players on the field, and a standard game lasts 9 innings. In science, 9 is the atomic number of fluorine, a highly reactive element used in toothpaste to help protect teeth from decay.
