Why is Long Division Important?
Long division is an essential mathematical theory which has several uses in distinguished domains, involving finance, engineering, and science. It is a fundamental mathematics function that is applied to work out a broad spectrum of challenges, for instance, calculating interest rates, measuring the length of time needed to complete a project, and determining the distance traveled by an object.
Long division is further applied in algebra to factor polynomials and solve equations. It is an important tool for working out complex challenges which involve huge numbers and requires accurate calculations.
Procedures Involved in Long Division
Here are the steps 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: Figure out 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 outcome 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. Write the remainder (the value left over after the division) underneath the subtraction.
Step 5: Carry 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 processed.
Examples of Long Division
Here are some examples of long division:
Example 1: Divide 562 by 4.
Solution:
140
--------
4 | 562
4
--
16
16
---
2
Therefore, 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.
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 concept to conquer, and there are many common errors that students make when working with long division. One usual mistake is to forget to write down the remainder when dividing. Another usual mistake is to incorrectly put the decimal point while dividing decimal numbers. Students may also forget to carry over figures while subtracting the product within the dividend.
To avoid making these mistakes, it is essential to exercise long division daily and pay close attention to ever stage of the process. It can further be helpful to check your work utilizing a calculator or by performing the division in reverse to make sure that your result is right.
In addition, it is essential to comprehend the fundamental principles behind long division, for example, the link between the quotient, dividend, divisor, and remainder. By conquering the fundamentals of long division and preventing common errors, everyone can improve their skills and gather confidence in their skill to work out complicated challenges.
Conclusion
Ultimately, long division is an essential mathematical theory that is important for working out complex problems in many domains. It is utilized in finance, engineering, science, and math, making it an essential skill for working professionals and learners alike.
