The TIMES TABLES
An easy way to remember the 9 times tables is
example: 5x9=45 just do 10x5=50 then take away 5 you will get the answer. 8 x9 just do 10 x 8 = 80 - 8 =72
The 10 times tables are easy if you can remember add a 0.
example: 76x10=760
To multily by 100 add two 00s. : example 26 x100=2600.
To multiply by 1000 add 3 000s : example 26X1000=26000
