Why is Long Division Important?
Long division is an important mathematical concept which has several applications in various fields, consisting of finance, engineering, and science. It is a fundamental math function which is used to work out a broad range of problems, such as figuring out interest rates, determining the length of time required to complete a project, and determining the distance traveled by an object.
Long division is also utilized in algebra to factor polynomials and solve equations. It is an important tool for solving intricate problems that involve huge numbers and need precise calculations.
Stages 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 could 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 result 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 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 few 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.
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.
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 challenging concept to master, and there are many general mistakes that learners make when performing long division. One common error is to forget to note down the remainder when dividing. One more common mistake is to incorrectly place the decimal point while dividing decimal numbers. Students might further forget to carry over figures when subtracting the product from the dividend.
To prevent making these errors, it is crucial to practice long division daily and ready carefully each step of the procedure. It can further be helpful to check your work utilizing a calculator or by working the division in reverse to assure that your result is correct.
Furthermore, it is important to get a grasp of the rudimental principles about long division, such as the relationship among the dividend, divisor, quotient, and remainder. By mastering the basics of long division and preventing usual mistakes, individuals can improve their abilities and obtain self-esteem in their ability to figure out intricate challenges.
Conclusion
