Why is Long Division Important?
Long division is a crucial mathematical concept which has several applications in various domains, involving engineering, science and finance. It is a fundamental math operation that is utilized to solve a wide array of problems, for example, calculating interest rates, measuring the length of time required to finish a project, and finding the length traveled by an object.
Long division is further used in algebra to factor polynomials and solve equations. It is an essential tool for working out intricate challenges which include huge numbers and requires precise calculations.
Steps Involved in Long Division
Here are the steps involved in long division:
Step 1: Write the dividend (the number being divided) on the left and the divisor (the value dividing the dividend) on the left.
Step 2: Calculate 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 note down the outcome beneath the digit or set of digits.
Step 4: Subtract the outcome obtained in step 3 from the digit or set of digits in the dividend. Write the remainder (the amount left over after the division) below the subtraction.
Step 5: Bring down the following digit or set of digits from the dividend and append it to the remainder.
Step 6: Replicate steps 2 to 5 unless all the digits in the dividend have been refined.
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
Therefore, 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
Therefore, 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
So, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a problematic theory to conquer, and there are numerous general mistakes which learners make when performing long division. One general error is to forget to write down the remainder when dividing. One more common mistake is to incorrectly place the decimal point when dividing decimal numbers. Students may also forget to carry over figures while subtracting the product from the dividend.
To circumvent making these mistakes, it is crucial to exercise long division regularly and pay close attention to ever stage of the process. It can also be beneficial to check your calculations utilizing a calculator or by performing the division in reverse to assure that your answer is right.
Furthermore, it is essential to get a grasp of the rudimental principles regarding long division, such as the connection among the quotient, dividend, divisor, and remainder. By mastering the essentials of long division and avoiding common mistakes, everyone can improve their skills and gather confidence in their ability to figure out complex challenges.
Conclusion
Finally, long division is an essential mathematical theory that is important for figuring out complicated problems in several domains. It is utilized in engineering, science, finance, and mathematics, making it an essential ability for working professionals and students alike.
