Today I learnt...

Today I learnt how to do prime numbers and factors. Prime numbers are thing that can only be multiplied by 1 problem, like 2 is a prime because it can only be made by 1 x 2. Factors are the numbers that are used to make a number like 4 has 3 factors, 1, 4 and 2. 1 x 4 = 4 and 2 x 2 = 4. You can't have to factors the same. A prime only has 2 factors because it can only be made by 1 equation, remember? 1 isn't a prime number because the only way to make it is 1 x 1. That is only 1 factor because a number cannot have 2 factors the same so it equals as 1. That is kind of confusing but that is what I learnt.
