Why is Long Division Important?
Long division is a crucial math concept which has numerous utilization in different fields, including engineering, science and finance. It is an important math function which is utilized to figure out a broad range of challenges, such as working out interest rates, measuring the amount of time needed to complete a project, and determining the distance traveled by an object.
Long division is further utilized in algebra to factor polynomials and work out equations. It is an important tool for working out complicated problems which involve huge values and requires accurate calculations.
Procedures Involved in Long Division
Here are the procedures 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: Figure out how many times the divisor could be divided into the first digit or set of digits of the dividend. Write 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 obtained in step 3 from the digit or set of digits in the dividend. Note down 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
As a result, 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.
Solution:
41
-----
83 | 3475
3326
----
149
124
---
25
So, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a difficult idea to master, and there are numerous general errors which students make when working with long division. One usual error is to forget to note down the remainder when dividing. Another usual error is to incorrectly position the decimal point while dividing decimal numbers. Learners may also forget to carry over numbers when subtracting the product from the dividend.
To prevent making these mistakes, it is essential to exercise long division daily and be mindful of each stage of the process. It can also be beneficial to revisit your calculations utilizing a calculator or by working the division in reverse to make sure that your answer is correct.
Additionally, it is essential to comprehend the fundamental principles about long division, for example, the connection among the quotient, dividend, divisor, and remainder. By conquering the essentials of long division and preventing common mistakes, individuals can better their abilities and gain confidence in their ability to solve intricate challenges.
