Why is Long Division Important?
Long division is a crucial mathematical theory that has numerous applications in various domains, including engineering, science and finance. It is an important arithmetic function which is applied to solve a wide array of challenges, for instance, calculating interest rates, determining the amount of time needed to finish a project, and finding the length traveled by an object.
Long division is also applied in algebra to factor polynomials and work out equations. It is an important tool for working out complex problems which consist of enormous values and need precise calculations.
Stages Involved in Long Division
Here are the stages involved in long division:
Step 1: Note the dividend (the number 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 below the digit or set of digits.
Step 4: Subtract the outcome achieved in step 3 from the digit or set of digits in the dividend. Write the remainder (the value left over after the division) underneath 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 refined.
Examples of Long Division
Here are few examples of long division:
Example 1: Divide 562 by 4.
Workings:
140
--------
4 | 562
4
--
16
16
---
2
As a result, 562 divided by 4 is 140 with a remainder of 2.
Example 2: Divide 1789 by 21.
Solution:
85
-----
21 | 1789
21
---
158
147
---
11
Therefore, 1789 divided by 21 is 85 with a remainder of 11.
Example 3: Divide 3475 by 83.
Workings:
41
-----
83 | 3475
3326
----
149
124
---
25
So, 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 many ordinary errors which learners make when performing long division. One general mistake is to forget to note down the remainder when dividing. One more usual mistake is to incorrectly put the decimal point when dividing decimal numbers. Learners might also forget to carry over numbers while subtracting the product from the dividend.
To prevent making these errors, it is crucial to exercise long division frequently and pay close attention to each stage of the process. It can further be helpful to revisit your calculations using a calculator or by performing the division in reverse to ensure that your answer is correct.
Additionally, it is essential to get a grasp of the rudimental principles about long division, for instance, the connection among the divisor, quotient, dividend, and remainder. By mastering the basics of long division and avoiding usual errors, anyone can better their skills and gain confidence in their skill to solve complex challenges.
Conclusion
In conclusion, long division is a crucial mathematical idea that is important for solving complicated challenges in various domains. It is applied in finance, engineering, science, and mathematics, making it an important skill for professionals and learners alike.
