Why is Long Division Important?
Long division is an important math theory which has numerous utilization in various fields, consisting of engineering, science and finance. It is an essential mathematics operation which is used to solve a broad spectrum of challenges, for example, figuring out interest rates, determining the length of time required to finish a project, and figuring out the distance traveled by an object.
Long division is further utilized in algebra to factor polynomials and figure out equations. It is a crucial tool for figuring out intricate challenges that include huge numbers and requires precise calculations.
Procedures Involved in Long Division
Here are the stages involved in long division:
Step 1: Write 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 result achieved in step 3 from the digit or set of digits in the dividend. Write the remainder (the amount left over 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 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.
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
As a result, 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
Therefore, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a difficult concept to master, and there are numerous ordinary mistakes which learners make when working with long division. One common error is to forget to note down the remainder when dividing. Another usual mistake is to incorrectly position the decimal point while dividing decimal numbers. Learners might also forget to carry over values when subtracting the product within the dividend.
To prevent making these errors, it is crucial to exercise long division daily and ready carefully ever step of the procedure. It can further be beneficial to revise your calculations utilizing a calculator or by performing the division in reverse to ensure that your result is correct.
Additionally, it is important to understand the rudimental principles behind long division, for instance, the connection between the divisor, quotient, dividend, and remainder. By conquering the fundamentals of long division and avoiding common mistakes, everyone can enhance their skills and obtain confidence in their ability to solve intricate problems.
