Why is Long Division Important?
Long division is a crucial math concept that has numerous applications in distinguished fields, involving engineering, science and finance. It is a fundamental mathematics operation that is applied to figure out a wide spectrum of problems, for instance, figuring out interest rates, measuring the amount of time needed to complete a project, and figuring out the length traveled by an object.
Long division is also utilized in algebra to factor polynomials and solve equations. It is a crucial tool for figuring out complex challenges which involve large values and need exact calculations.
Stages 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: Determine how many times the divisor could be divided into the first digit or set of digits of the dividend. Note down 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 remaining after the division) below the subtraction.
Step 5: Bring 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 some examples of long division:
Example 1: Divide 562 by 4.
Solution:
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.
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
Thus, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a problematic concept to conquer, and there are numerous general mistakes that 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 wrongly put the decimal point while dividing decimal numbers. Learners may further forget to carry over numbers while subtracting the product within the dividend.
To avoid making these errors, it is important to practice long division frequently and be mindful of each stage of the process. It can further be helpful to revise your work utilizing a calculator or by working the division in reverse to ensure that your answer is correct.
Additionally, it is important to comprehend the rudimental principles regarding long division, for instance, the link between the quotient, dividend, divisor, and remainder. By conquering the fundamentals of long division and preventing usual errors, everyone can enhance their skills and gain self-esteem in their skill to work out complicated challenges.
Conclusion
Finally, long division is an essential mathematical theory which is essential for figuring out complicated challenges in many fields.
