Why is Long Division Important?
Long division is an important mathematical theory that has many applications in different fields, involving engineering, science and finance. It is a fundamental mathematics function which is applied to figure out a broad range of problems, for example, calculating interest rates, measuring the amount of time needed to complete a project, and finding the distance traveled by an object.
Long division is further applied in algebra to factor polynomials and figure out equations. It is a crucial tool for figuring out complicated problems which consist of enormous numbers and need accurate calculations.
Procedures Involved in Long Division
Here are the stages involved in long division:
Step 1: Write the dividend (the value being divided) on the left and the divisor (the number dividing the dividend) on the left.
Step 2: Figure out how many times the divisor can be divided into the first digit or set of digits of the dividend. Note down the quotient (the outcome of the division) prior the digit or set of digits.
Step 3: Multiply the quotient by the divisor and write the outcome beneath the digit or set of digits.
Step 4: Subtract the result obtained in step 3 from the digit or set of digits in the dividend. Write the remainder (the amount remaining after the division) below the subtraction.
Step 5: Bring down the next digit or set of digits from the dividend and append it to the remainder.
Step 6: Repeat steps 2 to 5 unless all the digits in the dividend have been processed.
Examples of Long Division
Here are handful of examples of long division:
Example 1: Divide 562 by 4.
Solution:
140
--------
4 | 562
4
--
16
16
---
2
Thus, 562 divided by 4 is 140 with a remainder of 2.
Example 2: Divide 1789 by 21.
Workings:
85
-----
21 | 1789
21
---
158
147
---
11
As a result, 1789 divided by 21 is 85 with a remainder of 11.
Example 3: Divide 3475 by 83.
Solution:
41
-----
83 | 3475
3326
----
149
124
---
25
Thus, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a challenging concept to conquer, and there are several common mistakes that learners make when working with long division. One general error is to forget to note down the remainder when dividing. One more usual mistake is to incorrectly position the decimal point when dividing decimal numbers. Learners might also forget to carry over numbers while subtracting the product within the dividend.
To circumvent making these errors, it is essential to work on long division regularly and pay close attention to each step of the procedure. It can also be helpful to revise your work using a calculator or by performing the division in reverse to make sure that your result is correct.
Additionally, it is crucial to comprehend the basic principles regarding long division, for example, the connection between the quotient, dividend, divisor, and remainder. By mastering the fundamentals of long division and preventing common mistakes, individuals can improve their skills and gain confidence in their ability to work out intricate problems.
