These are some study notes for maths. When doing maths, I like to use these as help when I am trying to remember something like the strategy or technique.
Factors
Meaning = Factors are what number times another number equal to the answer. E.g:
24 = what 2 numbers multiplied equals to the equation but in this case 24. Factors like 2 and 12 equals to 24 because... 2x12=24
The factors:
21 = 7, 3, 1, 21
48 = 1, 2, 3, 4, 6, 8, 12, 16, 48
16 = 1, 2, 4, 8
24 = 1, 2, 3, 4, 6, 8, 12
Prime Numbers:
Meaning = Prime numbers are numbers that are divisible only by itself and 1
Prime numbers = 2, 3, 5, 7, 11
