Multiplying is finding the whole, it is adding equal parts, it is a way of simplifying the addition. If you add:
If you multiply 5 by the number of parcels, which is 4, we find the same result:
5 x 4 = 20
It is possible to multiply in another way, see:
4 x 5 = 20
We changed the order of the parcels and did not change the result. The result of multiplying between two or more numbers is called product.
Let's calculate?
Lucas collects carts, to organize he placed 9 carts on each of the 4 shelves of the bookcase in his room. How many carts are on the shelf?
Cart collection
If on each shelf there are 9 carts and there are 4 shelves, then we can do:
9 x 4 = 36
9 + 9 + 9 + 9 = 36
4 x 9 = 36
4 + 4 + 4+ 4 + 4 + 4+ 4 + 4 + 4= 36
There are 36 carts on the shelf.
What if Lucas wanted to know how many wheels each cart has?
As there are 36 carts and each cart has 4 wheels, so:
36 x 4 = 144 wheels
36 + 36 + 36 + 36 = 144
4 x 36 = 144 wheels
4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 = 36
Multiplication simplifies addition!
