Hello and welcome to basic multiplication this video you'll learn how to multiply numbers up to 10
First of all, what is multiplication?
Multiplication means to add the same number again and again and again
We write multiplication problems like this
3 times 2 is equal to 6 this
means that we're figuring out how many there are if we think of three twos or
two plus two plus two
other
multiplication problems work the same way for
instance 4 times 8 equals 32
this means that we're asking 8
groups of 4 so 4 plus 4 plus 4 plus 4 plus 4 plus 4 plus 4 plus 4
This is a lot shorter
You can think of multiplication as a shortcut instead of adding together all those fours. You can just write 4 times 8
Remember numbers can represent things for instance here. You see groups of three pieces of candy
How many groups do you see?
There are three groups of three items
If you count the items, you'll see that 3 times 3 is equal to 9
Multiplication problems are the same regardless of the order of the numbers being multiplied
Here you can see that two groups of four equals eight
For groups of two also equals eight
Some numbers are especially easy to multiply you may already be able to do it and not even know it
for instance
If you can count by fives, you can multiply it by five all multiples of five have to end in a 0 or a 5
In a similar way all multiples of 10 have to end in a 0 like 10 20 and 30
While multiplying harder numbers is more challenging than simple numbers the concept is the same
You're adding up groups of numbers
for instance
7 times 6 is equal to 42
that's 6 groups of 7 or 7 plus 7 plus 7 plus 7 plus 7 plus 7 if
You add seven more to that. It becomes 7 times 7 equals 49
7 times 7 is 49. So how much is 7 times 8?
7 times 8 is 56
Now let's add another 7 to get the answer to 7 times 9
Did you get 63?
What's 7 times 10, this one's easy count by tens if you need to
Yes, it's 70
a
Multiplication table is an easy way to memorize or remember the answers to multiplication problems
To use a multiplication table move across to the first number in the multiplication problem
Then move down to the second number in the multiplication problem
You'll have the answer
Learning how to use a table like this makes multiplication easier
However mental math matters so you'll want to memorize this multiplication table
Looking at the table, you can see that all multiplication problems work the same way
regardless of whether it's 2 times 2 or 9 times 9
