Why is Long Division Important?
Long division is an important math idea that has numerous uses in various fields, consisting of science, finance, engineering. It is a fundamental arithmetic function that is utilized to figure out a wide spectrum of challenges, such as calculating interest rates, measuring the length of time required to finish a project, and finding the length traveled by an object.
Long division is also used in algebra to factor polynomials and solve equations. It is an important tool for figuring out complex challenges that consist of huge numbers and need precise calculations.
Stages Involved in Long Division
Here are the stages involved in long division:
Step 1: Note the dividend (the number being divided) on the left and the divisor (the number 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. Write 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 outcome achieved in step 3 from the digit or set of digits in the dividend. Note down the remainder (the value left over after the division) underneath 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 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
So, 562 divided by 4 is 140 with a remainder of 2.
Example 2: Divide 1789 by 21.
Workings:
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.
Workings:
41
-----
83 | 3475
3326
----
149
124
---
25
So, 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 general mistakes which students make when performing long division. One usual error is to forget to note down the remainder when dividing. Another usual mistake is to wrongly place the decimal point while dividing decimal numbers. Students might also forget to carry over values while subtracting the product from the dividend.
To avoid making these errors, it is important to work on long division daily and ready carefully each step of the process. It can also be helpful to revisit your calculations using a calculator or by working the division in reverse to ensure that your answer is correct.
In addition, it is crucial to comprehend the fundamental principles about long division, for example, the link between the divisor, quotient, dividend, and remainder. By conquering the fundamentals of long division and avoiding common mistakes, individuals can enhance their skills and gather self-esteem in their skill to figure out intricate challenges.
Conclusion
Ultimately, long division is a fundamental math concept that is important for figuring out complex challenges in several fields. It is used in science, finance, engineering, and mathematics, making it an important ability for professionals and students alike.
