Why is Long Division Important?
Long division is an important math idea that has numerous uses in various fields, consisting of finance, engineering, and science. It is a fundamental math operation which is used to work out a broad range of problems, for instance, working out interest rates, determining the amount of time required to complete a project, and finding the distance traveled by an object.
Long division is further utilized in algebra to factor polynomials and work out equations. It is an essential tool for figuring out intricate challenges which include large numbers and requires precise calculations.
Procedures Involved in Long Division
Here are the stages 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: Determine how many times the divisor can be divided into the first digit or set of digits of the dividend. Write the quotient (the result 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 achieved in step 3 from the digit or set of digits in the dividend. Write 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: Replicate steps 2 to 5 until 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.
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.
Solution:
85
-----
21 | 1789
21
---
158
147
---
11
Therefore, 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 challenging theory to conquer, and there are numerous ordinary errors that learners make when working with long division. One usual mistake is to forget to note down the remainder when dividing. Another usual error is to wrongly put the decimal point while dividing decimal numbers. Learners may further forget to carry over figures when subtracting the product from the dividend.
To avoid making these errors, it is essential to exercise long division daily and be mindful of ever stage of the process. It can also be beneficial to check your work using a calculator or by working the division in reverse to ensure that your solution is correct.
Furthermore, it is important to comprehend the rudimental principles regarding long division, for example, the connection among the dividend, divisor, quotient, and remainder. By conquering the fundamentals of long division and avoiding common errors, everyone can better their skills and obtain self-esteem in their skill to solve complicated challenges.
Conclusion
