Definition. Division is the action of dividing something. Division consists of three parameters: the divisor, the divisor and the quotient. The divisible is what is being divided. The divisor is a number that shows how many parts to divide the divisible. The quotient is the actual result.
For example, suppose we have four apples:
Divide them equally among the two friends. Then the division will show how many apples each will get. It is easy to see that everyone will get two apples:
The process of dividing four apples by two friends can be described by the following expression:
In this example, the apples play the role of the divisible. The role of the divisor is played by two friends, showing how many parts to divide the 4 apples into. The role of the quotient is played by two apples, showing how many each got.
There are other ways to talk about division. Let us return to the previous expression 4 : 2 = 2. We can look at the divisor 2 and ask the question "how many twos are in a four?" and the answer is "two twos". Indeed, if we add two twos, we get the number 4
In the four-apple situation, you could ask the question "how many times two apples are contained in four apples" and answer, "two times".
To learn how to divide, you need to know the multiplication table well. Why multiplication? Because we are talking about division. The fact is that division is the inverse of multiplication. This phrase can be understood in the literal sense. For example, if 2 x 5 = 10, then 10 : 5 = 2.
You can see that the second expression is written in reverse order. If we have two apples and we want to increase them by a factor of five, we write 2 x 5 = 10. That would make ten apples. Then, if we want to put the ten apples back down to two apples, we write 10 : 5 = 2.
The division sign looks like a colon : but you can also find colons and dashes ?
In writing, it makes more sense to use a colon because it looks neater.
