Multiplication and Division Rules to help!
Multiplication and Division are opposites See the Family of Facts: 4 x 3 = ÷ 3 = 4
Its all about Groups Multiplication means groups of Division means share into groups e.g. 3 x 2 means 3 groups of 2 e.g. 6 ÷ 3 means 6 shared into 3 groups
Multiplying by 0 When you multiply by 0 the answer is always 0 e.g. 4 x 0 = 0 e.g. 57,000 x 0 = 0
Multiplying by 1 When you multiply a number by 1, the answer is always the same as the number e.g. 5 x 1 = 1 e.g. 3 x 1 = 3 e.g. 35 x 1 = 1 e.g. 23,000 x 1 = 23,000
Multiplying by 2 Multiplying by 2 is the same as Doubling or adding the number to itself e.g. 5 x 2 = 10 Double 5 is = 10
Dividing by 2 When you divide by 2 it is the same as halving the number e.g. 50 ÷ 2 = 25 Half of 50 is 25
Multiplying by 4 If you want to quickly multiply a number by 4, then just double it twice! e.g. 6 x 4 = 24 double 6 is 12 double 12 is 24
Multiplying by 5 The 5 times table is easy to learn, if you remember that all answers end in a 5 or a
Multiplying by 10 When you multiply by 10, all the digits move 1 place to the left and a 0 is added. X 10
