Why is Long Division Important?
Long division is a crucial math concept which has many uses in various domains, involving finance, engineering, and science. It is an essential math operation which is utilized to work out a wide array of problems, for example, figuring out interest rates, determining the amount of time required to complete a project, and determining the length traveled by an object.
Long division is also utilized in algebra to factor polynomials and work out equations. It is an important tool for figuring out complex challenges that include enormous numbers and need accurate calculations.
Stages Involved in Long Division
Here are the procedures involved in long division:
Step 1: Write 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. Write the quotient (the outcome of the division) above 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 obtained 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 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 few examples of long division:
Example 1: Divide 562 by 4.
Solution:
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
So, 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
Therefore, 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 numerous ordinary mistakes that learners make when working with long division. One general mistake is to forget to note down the remainder when dividing. One more common mistake is to wrongly put the decimal point when dividing decimal numbers. Students may also forget to carry over figures while subtracting the product from the dividend.
To avoid making these mistakes, it is essential to exercise long division daily and ready carefully each step of the procedure. It can further be beneficial to revisit your calculations using a calculator or by working the division in reverse to make sure that your solution is right.
Additionally, it is important to understand the rudimental principles behind long division, such as the link between the dividend, divisor, quotient, and remainder. By conquering the essentials of long division and preventing usual errors, individuals can enhance their skills and gather confidence in their ability to work out intricate problems.
Conclusion
Finally, long division is an essential math idea which is essential for figuring out complex problems in various fields.
