Why is Long Division Important?
Long division is an essential math theory that has several utilization in distinguished fields, including finance, engineering, and science. It is an important math function that is used to work out a wide array of challenges, such as working out interest rates, determining the length of time needed to complete a project, and finding the distance traveled by an object.
Long division is further utilized in algebra to factor polynomials and solve equations. It is an important tool for solving complicated problems that consist of large numbers and need precise calculations.
Procedures Involved in Long Division
Here are the steps 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 can be divided into the first digit or set of digits of the dividend. Write 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 outcome below 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 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: Repeat steps 2 to 5 until 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
Thus, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a difficult theory to conquer, and there are several general errors that learners make when performing long division. One usual mistake is to forget to note down the remainder when dividing. Another common error is to incorrectly place the decimal point while dividing decimal numbers. Learners may further forget to carry over numbers when subtracting the product within the dividend.
To circumvent making these mistakes, it is essential to practice long division frequently and be mindful of ever stage of the procedure. It can also be helpful to check your work utilizing a calculator or by performing the division in reverse to ensure that your solution is right.
Additionally, it is important to comprehend the basic principles about long division, for instance, the relationship between the quotient, dividend, divisor, and remainder. By conquering the fundamentals of long division and preventing common mistakes, everyone can better their skills and gain confidence in their ability to work out complex challenges.
Conclusion
In conclusion, long division is a fundamental mathematical concept which is important for solving complicated problems in many fields. It is utilized in science, finance, engineering, and math, making it a crucial skill for professionals and students alike.
