Why is Long Division Important?
Long division is an important math idea that has numerous applications in various fields, including science, finance, engineering. It is an essential mathematics function which is used to work out a wide spectrum of problems, for instance, figuring out interest rates, determining the amount of time needed to finish a project, and finding the length traveled by an object.
Long division is further used in algebra to factor polynomials and work out equations. It is an essential tool for figuring out intricate challenges that involve large values and requires exact calculations.
Steps Involved in Long Division
Here are the steps involved in long division:
Step 1: Note the dividend (the value being divided) on the left and the divisor (the value dividing the dividend) on the left.
Step 2: Determine how many times the divisor can be divided into the first digit or set of digits of the dividend. Write the quotient (the result of the division) above the digit or set of digits.
Step 3: Multiply the quotient by the divisor and note down the result below the digit or set of digits.
Step 4: Subtract the result achieved in step 3 from the digit or set of digits in the dividend. Note down the remainder (the amount left over after the division) underneath the subtraction.
Step 5: Carry down the next 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
As a result, 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.
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 difficult theory to conquer, and there are several general mistakes that students make when performing long division. One general mistake is to forget to write down the remainder when dividing. Another common mistake is to wrongly place the decimal point while dividing decimal numbers. Learners might further 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 daily and pay close attention to ever stage of the process. It can also be helpful to revisit your work utilizing a calculator or by working the division in reverse to make sure that your result is right.
Furthermore, it is important to get a grasp of the rudimental principles regarding long division, for instance, the relationship between the divisor, quotient, dividend, and remainder. By mastering the essentials of long division and preventing usual errors, everyone can better their abilities and gather self-esteem in their skill to figure out complicated problems.
Conclusion
Ultimately, long division is an essential math theory which is crucial for working out complex challenges in various domains. It is utilized in finance, engineering, science, and mathematics, making it an important skill for working professionals and learners alike. By conquering the procedure involved in long division and getting a grasp of how to use them to real-world challenges, anyone can gain a detailed understanding of the complicated functions of the world around us.
