Why is Long Division Important?
Long division is an essential math concept that has several applications in distinguished fields, consisting of engineering, science and finance. It is an important mathematics operation which is used to solve a wide array of problems, for example, calculating interest rates, determining the amount of time needed to complete a project, and determining the distance traveled by an object.
Long division is also utilized in algebra to factor polynomials and solve equations. It is an important tool for figuring out complex problems which include enormous values 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 number dividing the dividend) on the left.
Step 2: Determine 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 result beneath 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 remaining after the division) underneath 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 few 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
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
As a result, 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 numerous ordinary mistakes which students make when performing long division. One common mistake is to forget to write down the remainder when dividing. One more common mistake is to wrongly put the decimal point while dividing decimal numbers. Students may further forget to carry over values while subtracting the product within the dividend.
To avoid making these mistakes, it is important to exercise long division regularly and pay close attention to each step of the process. It can further be helpful to check your calculations using a calculator or by working the division in reverse to assure that your result is correct.
Furthermore, it is crucial to comprehend the basic principles about long division, for example, the link among the divisor, quotient, dividend, and remainder. By mastering the essentials of long division and avoiding common mistakes, individuals can better their skills and gather confidence in their skill to solve intricate problems.
Conclusion
Ultimately, long division is a fundamental math theory that is essential for working out complicated problems in various domains. It is applied in engineering, science, finance, and math, making it a crucial skill for working professionals and students alike.
