Got problems to understand the multiplication in your math classes at school? Well, you have arrived to the right place! Here you will find some basic concepts about the multiplication and exercise that you will find helpful to clarify your doubts for sure, with your math teacher's help and the proposed exercises as supporting material in the classes, you will understand better the multiplication concepts and you will have fun while you learn.
La multiplicación
¿Qué es?
Basically, it can be considerated as a repeat of a sum. For example, multiply 3x4, is like sum 3 four times: 3+3+3+3= 12
Is very important that you learn the multiplication table, like this, you will can make multiplications quiclky with just thinking about the multiplication table.
¿What is the name of the multiplication elements?
the multiplication terms are called factors (3x4) and the result is called product. (12)
How to multiply?
When the multiplication has only two factors, the number that we are going to sum is the multiplicand the number that we are going to sum and the multiplier to the times that we are going to sum it.
in the example that we have used, the multiplicand is 3, the multiplier is 4, and the product es 12, which is the result of sum 3 + 3 + 3 + 3 or multiply 3 x 4.
Long term multiplication
It is a special method to multiply large numbers (larger than 10) that only need your knowledge of the ten times multiplication table.
Example:
We want to multiply 612x24
First: we multiply 612x4= (2.248)
Second: we multiply 612x20= (12.640)
Last: we add them together: (2.448+12.640=14.688)
But there's a better way to do the multiplication.
To multiply 612 × 20 we only need to multiply 612 × 2 and place the result one column over (so it is the same as multiplying by 20).
Just be be careful about lining up the columns

Multiplications with more than two digits:
When you are multiplying more than two digit numbers, we just have to move over two spaces:
