Why is Long Division Important?
Long division is an essential math idea which has many utilization in distinguished fields, including engineering, science and finance. It is an essential mathematics operation that is applied to work out a wide range of problems, such as working out interest rates, measuring the amount of time required to finish a project, and finding the length traveled by an object.
Long division is also applied in algebra to factor polynomials and work out equations. It is an essential tool for solving complex challenges which include huge values and requires exact 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 value 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 outcome of the division) prior the digit or set of digits.
Step 3: Multiply the quotient by the divisor and write the result below 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 following digit or set of digits from the dividend and append it to the remainder.
Step 6: Replicate steps 2 to 5 unless all the digits in the dividend have been processed.
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
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 theory to conquer, and there are many common errors that students make when performing long division. One usual mistake is to forget to note down the remainder when dividing. Another common error is to incorrectly put the decimal point when dividing decimal numbers. Learners might further forget to carry over figures when subtracting the product within the dividend.
To prevent making these errors, it is important to exercise long division frequently and be mindful of each stage of the procedure. It can further be helpful to revisit your calculations using a calculator or by working the division in reverse to assure that your solution is correct.
In addition, it is important to understand the rudimental principles regarding long division, such as the connection between the quotient, dividend, divisor, and remainder. By conquering the basics of long division and preventing common mistakes, individuals can better their skills and obtain self-esteem in their skill to solve complicated problems.
Conclusion
Finally, long division is a fundamental math theory which is essential for solving complex challenges in many domains. It is used in science, finance, engineering, and mathematics, making it an important ability for professionals and learners alike.
