Why is Long Division Important?
Long division is a crucial mathematical concept that has many utilization in various domains, involving science, finance, engineering. It is a fundamental mathematics function that is used to figure out a wide array of problems, for example, figuring out interest rates, determining the amount of time required to complete a project, and determining the length traveled by an object.
Long division is further applied in algebra to factor polynomials and work out equations. It is an essential tool for working out complicated challenges that include large numbers and requires exact calculations.
Procedures Involved in Long Division
Here are the stages involved in long division:
Step 1: Write 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 could be divided into the first digit or set of digits of the dividend. Write the quotient (the outcome 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 value remaining after the division) underneath 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 unless 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
So, 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
So, 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
Therefore, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a difficult idea to conquer, and there are several general errors which learners make when working with long division. One common mistake is to forget to write down the remainder when dividing. One more common error is to incorrectly place the decimal point when dividing decimal numbers. Learners may also forget to carry over figures while subtracting the product within the dividend.
To prevent making these errors, it is crucial to practice long division daily and be mindful of ever stage of the procedure. It can also be beneficial to revise your calculations using a calculator or by performing the division in reverse to make sure that your result is right.
Additionally, it is essential to understand the basic principles regarding long division, such as the connection among the quotient, dividend, divisor, and remainder. By mastering the fundamentals of long division and avoiding common mistakes, individuals can better their skills and gather confidence in their ability to work out complex problems.
Conclusion
In conclusion, long division is a fundamental mathematical theory that is important for figuring out complicated challenges in several domains. It is utilized in engineering, science, finance, and mathematics, making it a crucial skill for professionals and learners alike.
