Properties of multiplications
The operation of multiply has a number of properties that we must know in order to facilitate and correctly solve the operations in which it is involved.
Comutative ownership means that the order of the factors does not change the product. That is to say, it does not matter if we multiply 2 x 3 or 3 x 2, since in both cases, the result will be equal to six.
This property can be applied to multiplications involving a larger number of factors. For example:
3 x 5 x 10 = 5 x 3 x 10 = 10 x 3 x 5 = 10 x 5 x 3 x 3 = 150
As you can see, any of the above combinations give the same resultTherefore, it is verified that the multiplications satisfy the commutative property.
The associative property states that the way of grouping the factors in a multiplication does not change the result of the multiplication.
(3 x 2) x 5 = 3 (2 x 5)
If we solve the parentheses we have that:
6 x 5 = 3 x 10
And finally, we arrive at the result that both multiplications give us a value of 30 even though we have solved the operations with different multiplication groupings. Again, it is verified that the associative property is satisfied.
To multiply a number by a sumIf the sum of the multiplications of that number by each of the addends is the result. Example:
2 x (4 + 6) = 2 x 4 + 2 x 6
Let's see if we get the same result from both equalities:
2 x 10 = 8 + 12
Indeed, we see that the equality is fulfilled and therefore, it is verified that the multiplications also enjoy the distributive property.
Rule of signs in multiplications
As with divisions, multiplication also involves a number of different sign rules to be complied with to know what sign the result of the operation will have.
Below is a summary of the possible combinations when multiplying two numbers:
- + x + = +
- - x - = +
- + x - = -
- - x + = -
You can use the associative property that we have seen above for to know the sign that a multiplication with more factors will have.
For example, let's see the sign that the multiplication will have:
-2 x 3 x (-6) = (-2 x 3) x (-6)
The first parenthesis will give us a negative number, which multiplied by another negative number, will give us a positive result:
(-6) x (-6) = 36
Below you will find a list of all the multiplication tables 1 to 9 for you to learn or refresh your memory in case you have forgotten any of them.
On each page you will find a multiplication table from 0 to 100 of each number for you to download or print, tricks to memorize them and a song for children to learn to multiply.
Multiplying by one is the easiest that there is because when we multiply by the unit, we obtain as a result the number by which we multiply. Easy, isn't it? 1 x 1257 = 1257. Very simple.
Table of 2
When multiplying by two, we must think that the result will give us an even number which will be exactly double of the number by which we multiply.
Don't miss our section dedicated to the multiplication table of the number 2.
Table of 3
In the case of the multiplication table of the number three, there is no trick to it We are not known to involve the use of our fingers, something that would give us away to the rest of the world who sees us performing operations in this unorthodox way.
