Why is Long Division Important?
Long division is an important math concept which has numerous utilization in distinguished fields, involving engineering, science and finance. It is a fundamental mathematics function which is used to figure out a broad spectrum of problems, for instance, working out interest rates, measuring the length of time required to finish a project, and figuring out the length traveled by an object.
Long division is also utilized in algebra to factor polynomials and figure out equations. It is a crucial tool for working out complicated challenges which consist of large numbers and need accurate calculations.
Procedures Involved in Long Division
Here are the procedures involved in long division:
Step 1: Note the dividend (the value 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. 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 note down the outcome 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. Write the remainder (the value 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 refined.
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
Therefore, 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
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 challenging concept to master, and there are many general mistakes which 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 wrongly put the decimal point when dividing decimal numbers. Learners may further forget to carry over values while subtracting the product within the dividend.
To circumvent making these mistakes, it is important to exercise long division regularly and pay close attention to ever stage of the process. It can further be beneficial to check your work utilizing a calculator or by working the division in reverse to assure that your answer is right.
Furthermore, it is important to get a grasp of the basic principles about long division, such as the relationship among the divisor, quotient, dividend, and remainder. By conquering the basics of long division and avoiding common mistakes, anyone can improve their abilities and gain self-esteem in their skill to solve complicated challenges.
Conclusion
Finally, long division is a fundamental mathematical idea which is crucial for working out complex challenges in several fields. It is utilized in finance, engineering, science, and math, making it an essential skill for professionals and students alike.
