Multiplication is fun and easy once you know how to do it. Here is how you do it.
Lets say you have 5 times 5. That means you would count by 5 5 times. Here is another way you still have the same problem so you would draw 5 sets of dots and then you count them all and it should be 25 dots.
Double Digit Multiplication
How do you do double digit multiplication ? Is this what you are wondering ? Well guess what it's actually really easy once you know how to do it.
Example
535
x85

Single digit multiplying
So first here is an example.
85
x 3
?
This is way easy. You just times 3 x 5 witch is 15 so you put down the 5 and carry the 1.
Next you times 3 x 8 + 1 witch equals 25.
And you should have 255 for the answer .
Multiplying zeroes
First an example
85
x 30
1. This is way easy. Cross off zero and put as much zeroes there is in the problem as there is in the answer.
2. Times 3 x 5 which is 15 , Put down the 5 and carry the 1.
3. Times 8x3 + 1 which is 25. Then your total should be 2550
