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:
Multiplication: It is like addition. For example, 1+1+1+1 is the same thing as 1 x 4, but multiplying is faster.
Division: It is the opposite of multiplication. For example, 12/4=__. All you need to know is what times 4 equals 12, and the answer to that is 3. So the answer is 3.
