Multiply and Divide Whole Numbers explain what to do and how to do it
rodikova [14]
Multiplication is a simple way of adding
For example 6x8 is the same as 8+8+8+8+8+8

Any number multiplied by 1 is itself E.g 4x1 = 4

Multiplying by 2 is just doubling

Multiplying by 10 is adding a 0 to the original number

If it is a big number that you do not know how to multiply mentally split it up
E.g 17x13
Split 13 into 10 and 3
17x10= 170
17x3= 51
Then add these numbers
221

If you ever get stuck, use the long method, add them instead, you will get to the right answer but it will take longer

Dividing is not as simple
Like multiplication dividing by one will leave you with the same answer

Dividing by two means you half the number, which may give you a decimal

Bigger numbers are trickier, and you may be allowed to use a calculator for numbers
Below are a number of links, these websites will teach you how to improve your multiplication and division skills:
