easy maths

1. Ten times table.

E.g 4x10= 4 wih zero added

312x10= 312 with zero added

=3120

2. five tlme tables

For even numbers- halve the number and add a zero

2x5 half of 2 is 1plus add a zero=10

4x5= half of 4 is 2 plus add a zero =20

12x5= half of 12 is 6plus add a zereo = 60
Odd numbers
Look a the even number below and put a 5 after it.

eg. 5x3=  (2)  half of 2 is 1, then put a 5 after it. = 15
        5x7 = (6) half of 6 is 3, then put a 5 after it =  35


I must know that even numbers are numbers that can divide into 2 evenly.
eg. 2, 4,  6, 8, 10, 12

Odd numbers cannot be divided evenly.
eg. 3, 5, 7, 9.,11
