Why do we divide?
The division is an operation inverse of multiplication. If 3 groups of 4 make 12 in multiplication; 12 divided into 3 equal groups give 4 in each group in division. The main goal of the division is to see how many equal groups or how many in each group when sharing fairly.Why do we divide and multiply?
Relating Multiplication and DivisionIn multiplication, the numbers being multiplied are called factors; the result of the multiplication is called the product. In division, the number being divided is the dividend, the number that divides it is the divisor, and the result of the division is the quotient.
Why do we need division in math?
Division allows us to divide or 'share' numbers to find an answer. For example, let's consider how we would find the answer to 10 ÷ 2 (ten divided by two).

A division equation is made up of three parts: The dividend is the number that's being divided (the first number in the problem). The divisor is the number the dividend is being divided by (the second number in the problem.) The quotient is the number of times the divisor will go into the dividend (the solution).Why do we divide first?
Applying BODMAS/PEMDAS correctly , M/D have equal precedence, and A/S have equal precedence. So, addition and subtraction , is done left to right. As is multiplication and division. The correct answer is subtraction first as it occurs first.What is the division fact?

This notation was introduced by Gottfried Wilhelm Leibniz in his 1684 Acta eruditorum.Who first used division?
The sign was first used to indicate division in mathematics in 1659 by Johann Heinrich Rahn, a Swedish mathematician, in his book, TeutscheAlgebr. He didn't say if it was supposed to be a blank fraction when he used it. Another fun fact: the obelus was also used at one point to indicate subtraction.Who invented 0?

If student gets below 60% but above 45% then it is said to be second division.Why is learning long division important?
The long division algorithm is the essential tool in establishing that any rational number has a repeating block of digits in its decimal representation. The converse, that any decimal with a repeating block is equal to a rational number, requires a different argument.Why do we divide from left to right?
Ultimately, though, we divide left to right simply because that has been found to be the most efficient way to do it. It is the collected wisdom of several centuries, not something that was forced on us by the way numbers work.
