TYPES OF NUMBER
Yesterday, we looked at Prime numbers. Can you remember the definition of a prime number?
PRIME NUMBERS:
a number that only has 2 factors, 1 and itself.
e.g 2, 3, 7, 11….
Today we will be recapping different types of number including:
SQUARE NUMBERS:
a number multiplied by itself
e.g. 2 x 2 = 4
So 4 is a square number.
√ is the symbol for square root, so you work backwards!
√ 64 is 8 because 8 x 8 = 64
CUBE NUMBERS:
a number multiplied by itself twice
e.g. 2 x 2 x 2 = 8
So 8 is a cube number.
MULTIPLES:
multiples of a number are the timestables of that number.
e.g. 5 x 5 = 25
So 25 is a multiple of 5.
FACTORS:
a factor is a number that can divide equally into another number without leaving a remainder.
e.g. 10 ÷ 2 = 5
So 2 and 5 are both factors of 10.
