Why is Long Division Important?
Long division is a crucial mathematical idea which has numerous applications in various fields, including finance, engineering, and science. It is an important mathematics function which is used to figure out a broad range of challenges, for example, working out interest rates, determining the amount of time required to complete a project, and figuring out the distance traveled by an object.
Long division is also applied in algebra to factor polynomials and solve equations. It is a crucial tool for working out complicated problems that involve large numbers and requires precise calculations.
Steps 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: Calculate how many times the divisor can be divided into the first digit or set of digits of the dividend. Write 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 result beneath 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 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: Repeat steps 2 to 5 unless 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.
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.
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 problematic idea to master, and there are many ordinary mistakes that students make when performing long division. One general mistake is to forget to note down the remainder when dividing. Another usual mistake is to incorrectly position the decimal point when dividing decimal numbers. Students might further forget to carry over figures when subtracting the product within the dividend.
To avoid making these mistakes, it is essential to exercise long division frequently and be mindful of each stage of the procedure. It can further be helpful to revisit your work utilizing a calculator or by working the division in reverse to assure that your answer is correct.
In addition, it is crucial to comprehend the fundamental principles regarding long division, such as the connection between the dividend, divisor, quotient, and remainder. By conquering the essentials of long division and preventing usual mistakes, everyone can improve their skills and gain confidence in their ability to figure out intricate problems.
Conclusion
