Why is Long Division Important?
Long division is an essential math idea that has several uses in distinguished fields, including finance, engineering, and science. It is a fundamental math function which is applied to figure out a broad spectrum of challenges, for example, calculating interest rates, measuring the amount of time needed to complete a project, and finding the distance traveled by an object.
Long division is also utilized in algebra to factor polynomials and work out equations. It is an important tool for figuring out complicated challenges which involve enormous values and requires precise calculations.
Stages 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. 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 value left over after the division) below the subtraction.
Step 5: Carry down the following 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 refined.
Examples of Long Division
Here are handful of examples of long division:
Example 1: Divide 562 by 4.
Workings:
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
As a result, 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
Therefore, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a problematic theory to master, and there are several common errors which students make when performing long division. One general error is to forget to write down the remainder when dividing. Another common mistake is to incorrectly place the decimal point while dividing decimal numbers. Students may also forget to carry over figures while subtracting the product from the dividend.
To avoid making these mistakes, it is important to work on long division regularly and be mindful of ever step of the procedure. It can further be helpful to check your work utilizing a calculator or by performing the division in reverse to ensure that your answer is right.
In addition, it is crucial to get a grasp of the rudimental principles regarding long division, for instance, the connection among the dividend, divisor, quotient, and remainder. By conquering the basics of long division and preventing usual errors, everyone can improve their skills and gather self-esteem in their ability to work out intricate problems.
Conclusion
Finally, long division is a crucial math theory that is crucial for working out complicated challenges in many domains. It is used in engineering, science, finance, and math, making it a crucial skill for professionals and students alike. By mastering the steps involved in long division and understanding how to apply them to practical problems, everyone can get a deeper comprehension of the complex functions of the world surrounding us.
