Why is Long Division Important?
Long division is an important mathematical theory which has several utilization in distinguished domains, involving finance, engineering, and science. It is a fundamental arithmetic function that is applied to figure out a wide spectrum of challenges, for example, working out interest rates, determining the amount of time required to finish a project, and figuring out the distance traveled by an object.
Long division is further applied in algebra to factor polynomials and solve equations. It is a crucial tool for figuring out complicated challenges which consist of huge values and need exact calculations.
Procedures Involved in Long Division
Here are the stages involved in long division:
Step 1: Write 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. Write 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 below 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. Note down the remainder (the amount left over 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 until 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
Therefore, 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
Thus, 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 concept to conquer, and there are numerous general mistakes that students make when working with long division. One usual mistake is to forget to write down the remainder when dividing. Another usual error is to incorrectly put the decimal point when dividing decimal numbers. Students might further forget to carry over values when subtracting the product from the dividend.
To circumvent making these mistakes, it is essential to practice long division daily and be mindful of each stage of the process. It can also be helpful to revisit your calculations utilizing a calculator or by performing the division in reverse to assure that your solution is right.
In addition, it is crucial to comprehend the fundamental principles behind long division, for example, the relationship between the dividend, divisor, quotient, and remainder. By mastering the basics of long division and avoiding common errors, anyone can better their abilities and gain self-esteem in their skill to solve complicated challenges.
Conclusion
In conclusion, long division is an essential mathematical theory which is essential for solving complicated problems in various fields. It is utilized in finance, engineering, science, and mathematics, making it a crucial ability for working professionals and students alike.
