Understanding Multiplication 0, 1, 2

2
What is Multiplication?
Well Multiplication is the opposite of Division, in the same way that Addition is the opposite of Multiplication
To multiply means to add equal groups. When we multiply, the number of things in the group increases.
Example: 2×10=20
3
Multiplying with 0
Any number multiplied by 0 will always be 0
So whenever you see a number being multiplied by 0 just remember the answer will always be 0
For example is the problem 2×0=
You would know that you would have 2 groups of 0, meaning your answer would be 0
4
Multiplying with 1
Any number Multiplied by 1 will always be that number
So whenever you see a number being Multiplied by 1 just know the answer will be that number
An example being 1×8=
So you would know that you would have 1 group of 8. Meaning that your answer would be 8

Multiplying with 2
The easiest way to remember your 2 Multiplication table is that it will always be an even number
By even numbers it means your answer should always end in either a 0,2,4,6, or 8
If you can't do it off the top of your head you can always just count by 2's
8
Multiplying with 2 Continued
An example of a problem would be
2×10=So by looking at the question you would know that you would have 2 groups of 10s
Meaning that your answer would be 20
9
Multiplying with 2 using Arrays
Another way you can solve your Multiplication problems would be to use arrays
An Array is a way to represent Multiplication and Division using rows and columns. Rows(go across from left to right) represent the number of groups. Columns(go up and down) represent the number in each group or the size of each group.

Multiplying with 2 using Arrays Continued
So by using the Arrays you would count all the dots or circles in your Array in order to find your answer
