Why is Long Division Important?
Long division is an important math theory that has several utilization in various domains, involving engineering, science and finance. It is an essential math operation that is used to solve a broad array of problems, for instance, working out interest rates, determining the amount of time required to complete a project, and finding the length traveled by an object.
Long division is also applied in algebra to factor polynomials and solve equations. It is an essential tool for figuring out intricate problems that include huge numbers and need 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: Calculate how many times the divisor could be divided into the first digit or set of digits of the dividend. Note down the quotient (the result of the division) above 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 outcome obtained in step 3 from the digit or set of digits in the dividend. Write the remainder (the amount remaining after the division) underneath the subtraction.
Step 5: Carry down the following digit or set of digits from the dividend and append it to the remainder.
Step 6: Replicate 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
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
Thus, 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
As a result, 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 many common mistakes that learners make when working with long division. One general mistake is to forget to note down the remainder when dividing. One more common error is to incorrectly place the decimal point when dividing decimal numbers. Students may also forget to carry over figures when subtracting the product from the dividend.
To prevent making these mistakes, it is important to exercise long division frequently and be mindful of each stage of the process. It can also be helpful to check your calculations using a calculator or by performing the division in reverse to ensure that your answer is correct.
In addition, it is important to understand the fundamental principles behind long division, such as the connection among the dividend, divisor, quotient, and remainder. By conquering the essentials of long division and avoiding common errors, individuals can improve their abilities and obtain self-esteem in their ability to solve complicated problems.
Conclusion
In conclusion, long division is an essential math idea that is important for working out complicated problems in many domains. It is utilized in engineering, science, finance, and math, making it a crucial skill for professionals and students alike.
