Why is Long Division Important?
Long division is an important math theory which has several applications in distinguished fields, involving science, finance, engineering. It is an important math function which is used to work out a broad array of challenges, for instance, figuring out interest rates, measuring the length of time needed to finish a project, and finding the distance traveled by an object.
Long division is also utilized in algebra to factor polynomials and figure out equations. It is an essential tool for working out intricate problems that include huge values and need exact calculations.
Steps Involved in Long Division
Here are the steps involved in long division:
Step 1: Write the dividend (the value being divided) on the left and the divisor (the number 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 result of the division) prior 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 amount remaining after the division) below 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 until 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
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
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
Thus, 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 several common mistakes which students make when working with long division. One usual error is to forget to write down the remainder when dividing. One more usual mistake is to wrongly position the decimal point when dividing decimal numbers. Learners might further forget to carry over values while subtracting the product within the dividend.
To avoid making these mistakes, it is important to work on long division daily and ready carefully each stage of the process. It can further be beneficial to revisit your calculations using a calculator or by performing the division in reverse to make sure that your answer is correct.
Additionally, it is crucial to get a grasp of the fundamental principles regarding long division, for instance, the relationship between the dividend, divisor, quotient, and remainder. By mastering the fundamentals of long division and preventing usual mistakes, everyone can improve their abilities and gain self-esteem in their skill to figure out intricate challenges.
Conclusion
Ultimately, long division is a crucial math concept which is crucial for working out complicated problems in several domains. It is utilized in engineering, science, finance, and math, making it an important ability for professionals and learners alike. By conquering the stages involved in long division and understanding how to utilize them to practical problems, individuals can gain a detailed understanding of the complex functions of the world around us.
