Why is Long Division Important?
Long division is an important math idea which has several utilization in distinguished fields, involving engineering, science and finance. It is a fundamental arithmetic operation which is applied to work out a wide range of challenges, for instance, figuring out interest rates, measuring the amount of time required to finish a project, and figuring out the distance traveled by an object.
Long division is further used in algebra to factor polynomials and figure out equations. It is a crucial tool for figuring out intricate problems that involve large values and requires exact calculations.
Procedures Involved in Long Division
Here are the steps involved in long division:
Step 1: Note the dividend (the number being divided) on the left and the divisor (the value dividing the dividend) on the left.
Step 2: Determine how many times the divisor can be divided into the first digit or set of digits of the dividend. Note down the quotient (the outcome 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 obtained in step 3 from the digit or set of digits in the dividend. Note down the remainder (the amount remaining after the division) below the subtraction.
Step 5: Carry down the next digit or set of digits from the dividend and append it to the remainder.
Step 6: Repeat steps 2 to 5 until all the digits in the dividend have been processed.
Examples of Long Division
Here are some 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
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
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 idea to conquer, and there are numerous general mistakes that students make when performing long division. One common error is to forget to note down the remainder when dividing. One more usual error is to wrongly position the decimal point while dividing decimal numbers. Learners might also forget to carry over figures while subtracting the product within the dividend.
To circumvent 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 revisit your calculations utilizing a calculator or by performing the division in reverse to ensure that your answer is right.
In addition, it is important to get a grasp of the rudimental principles about long division, such as the link among the divisor, quotient, dividend, and remainder. By mastering the fundamentals of long division and preventing common errors, everyone can enhance their abilities and gain confidence in their skill to work out complicated problems.
Conclusion
In conclusion, long division is a crucial mathematical idea which is important for working out complex problems in several domains. It is used in engineering, science, finance, and math, making it an important skill for professionals and learners alike.
