Why is Long Division Important?
Long division is an important math theory that has numerous utilization in different domains, consisting of science, finance, engineering. It is a fundamental mathematics function which is utilized to work out a broad array of challenges, for instance, working out interest rates, measuring the length of time needed to finish a project, and finding the distance traveled by an object.
Long division is further used in algebra to factor polynomials and solve equations. It is a crucial tool for figuring out complex problems that consist of large values and need precise calculations.
Steps Involved in Long Division
Here are the steps involved in long division:
Step 1: Write the dividend (the value being divided) on the left and the divisor (the value 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 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. Note down the remainder (the value 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: Repeat steps 2 to 5 unless 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.
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
So, 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
As a result, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a problematic theory to master, and there are several ordinary errors that learners make when performing long division. One common mistake is to forget to note down the remainder when dividing. One more usual error is to wrongly position the decimal point while dividing decimal numbers. Learners may further forget to carry over numbers while subtracting the product from the dividend.
To prevent making these errors, it is crucial to practice long division daily and pay close attention to each stage of the procedure. It can also be helpful to revise your calculations using a calculator or by working the division in reverse to make sure that your result is right.
Additionally, it is essential to get a grasp of the basic principles regarding long division, for example, the relationship between the divisor, quotient, dividend, and remainder. By mastering the essentials of long division and preventing common mistakes, anyone can better their abilities and obtain self-esteem in their ability to solve complicated challenges.
