Why is Long Division Important?
Long division is an essential mathematical idea which has many applications in various fields, consisting of science, finance, engineering. It is an important mathematics function that is used to solve a broad range of challenges, such as working out interest rates, measuring the amount of time needed to finish a project, and figuring out the distance traveled by an object.
Long division is also used in algebra to factor polynomials and solve equations. It is a crucial tool for working out complicated problems which include large numbers and requires accurate calculations.
Procedures 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 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 outcome of the division) prior 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 value left over 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 few examples of long division:
Example 1: Divide 562 by 4.
Workings:
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.
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
Thus, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a difficult theory to master, and there are many ordinary errors that learners make when performing long division. One usual mistake is to forget to write down the remainder when dividing. Another common error is to incorrectly position the decimal point while dividing decimal numbers. Students may further forget to carry over numbers while subtracting the product from the dividend.
To avoid making these errors, it is essential to work on long division regularly and be mindful of each step of the process. It can also be beneficial to check your calculations utilizing a calculator or by performing the division in reverse to make sure that your solution is correct.
In addition, it is essential to comprehend the rudimental principles about long division, for example, the connection between the dividend, divisor, quotient, and remainder. By mastering the essentials of long division and preventing common errors, everyone can better their skills and obtain self-esteem in their ability to solve complicated problems.
Conclusion
Finally, long division is a crucial mathematical idea which is crucial for figuring out complex problems in many fields. It is applied in science, finance, engineering, and mathematics, making it an essential ability for professionals and learners alike.
