Why is Long Division Important?
Long division is an important mathematical concept that has many applications in different fields, consisting of finance, engineering, and science. It is a fundamental math function that is applied to figure out a broad spectrum of problems, for instance, working out interest rates, determining the length of time needed to complete a project, and figuring out the length traveled by an object.
Long division is further used in algebra to factor polynomials and solve equations. It is an important tool for solving complex problems that include huge values and need exact calculations.
Stages Involved in Long Division
Here are the procedures involved in long division:
Step 1: Write 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 could 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 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 amount left over 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.
Solution:
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
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
Therefore, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a difficult idea to master, and there are many common errors which learners make when performing long division. One usual mistake is to forget to note down the remainder when dividing. One more common mistake is to incorrectly put the decimal point when dividing decimal numbers. Learners may also forget to carry over figures while subtracting the product from the dividend.
To avoid making these mistakes, it is important to work on long division frequently and ready carefully ever stage of the procedure. It can further be helpful to check your calculations using a calculator or by working the division in reverse to assure that your answer is right.
Additionally, it is important to get a grasp of the rudimental principles about long division, for example, the relationship between the quotient, dividend, divisor, and remainder. By mastering the basics of long division and avoiding common errors, individuals can enhance their abilities and obtain confidence in their ability to solve complicated problems.
Conclusion
