The order does not change the results

ex. a+b = b+a OR a x b = b x a

The order of operations performed in groups when adding or multiplying

Ex: 8+(2+10) =(8+2) +10

Ex: 6(3x4) = 3(4x6)

Numbers with factors other than the number itself and 1

Ex: 4, 6, 9,27,33,49, 72

Numbers having only 2 factors, the number itself and 1

Ex: 3, 5, 7, 11, 13, 17

NOTE: 1 is NOT included

• these numbers can be odd or even
• the only factors are 1 and the number itself
• has an infinite number of multiples

Writing a number as the product of a power of 10

Ex:240.2 = 2.402 x 10²

Ex: 2,400,000 = 2.4 x 10⁶

The time tables for a number.

Ex: 9:18, 27, 36, 45, 54...

Ex: 5:10, 15, 20, 25, 30...

The smallest number that is a multiple of 2 or more numbers

EX: 15 is the smallest number that both 3 and 5 can go into

(3:3, 6, 9, 12, 15, 18...)

(5:5, 10, 15, 20, 25...)

Writing the number as only the product of prime numbers

Using a factor tree to find the answer

Distributing numbers without changing the results

Distributing numbers as they are taken apart

Ex: a(b+c) = (axb) + (axc)

Ex: 3(4+8) = (3x4) +(3x8)
