## How to calculate a division?

Division is a fundamental mathematical operation that describes the action of splitting a whole into equal parts. For example, if you divide 12 by 4 (written as 12 ÷ 4 or 12/4), you're splitting the number 12 into 4 equal parts, with each part being 3.

### The process of division

Division is a two-step process:

1. First, identify the numbers you want to divide. The number being divided is called the dividend and the number by which you are dividing is called the divisor. In the example 12 ÷ 4, 12 and 4 are the dividend and divisor, respectively.
2. Then, divide the dividend equally by the number specified by the divisor. The result of this operation is called the quotient. In the example 12 ÷ 4, 3 is the quotient.

### The properties of division

Division has several important properties that make working with this operation easier:

• Non-Commutativity: Unlike addition and multiplication, division is not commutative. In other words, a ÷ b is not the same as b ÷ a. For example, 12 ÷ 4 is 3, but 4 ÷ 12 is 0.333.
• Non-Associativity: Division is also not associative. In other words, (a ÷ b) ÷ c is not the same as a ÷ (b ÷ c). For example, (12 ÷ 4) ÷ 2 is 1.5, but 12 ÷ (4 ÷ 2) is 6.
• Identity: Any number divided by 1 gives the original number. For example, 7 ÷ 1 is equal to 7.
• Zero Divisor: Any number divided by 0 is undefined. This is because there is no number that can be multiplied by 0 to get the original number.

Division is an essential mathematical skill used in a wide range of applications, from simple everyday calculations to complex mathematical and scientific problems. By understanding the process and properties of division, we can effectively handle a variety of mathematical challenges.
