Why is Long Division Important?
Long division is an important math theory which has many utilization in different fields, consisting of science, finance, engineering. It is an important arithmetic operation that is utilized to figure out a wide range of challenges, for instance, working out interest rates, measuring the amount of time required to complete a project, and determining the length 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 complex problems which include large values and need exact calculations.
Stages Involved in Long Division
Here are the procedures involved in long division:
Step 1: Write the dividend (the value being divided) on the left and the divisor (the value 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. Write the quotient (the result 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 result obtained in step 3 from the digit or set of digits in the dividend. Note down the remainder (the amount remaining 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: Replicate steps 2 to 5 unless all the digits in the dividend have been refined.
Examples of Long Division
Here are some 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
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
As a result, 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 numerous common errors which learners make when working with long division. One common mistake is to forget to note down the remainder when dividing. One more common mistake is to wrongly put the decimal point while dividing decimal numbers. Learners might also forget to carry over figures while subtracting the product within the dividend.
To avoid making these errors, it is important to work on long division daily and ready carefully each step of the procedure. It can also be helpful to check your calculations using a calculator or by performing the division in reverse to assure that your answer is right.
Furthermore, it is essential to understand the rudimental principles behind long division, for instance, the connection between the dividend, divisor, quotient, and remainder. By mastering the essentials of long division and avoiding usual mistakes, everyone can improve their skills and gather confidence in their skill to solve complicated challenges.
Conclusion
Finally, long division is a crucial mathematical theory that is crucial for figuring out complicated problems in various fields. It is applied in engineering, science, finance, and mathematics, making it a crucial ability for professionals and students alike.
