This week in math 10 we learned about prime numbers, composite numbers, division table and number tree.

we can use a division table to find the lowest common multiple (LCM) in a math problem. I can also find what prime numbers go into that number using the division table.

we can use a number tree to find out what prime numbers go into a big number, for example 620.

I did not know what a division table was until now, and I can say it is very helpful.
