The octal system, while less common than binary or hexadecimal in general programming, plays a crucial role in specific areas like Unix file permissions. It uses the number 8 as its base to denote the numbers. Also, it remains important in specific areas, such as setting file permissions in Unix/Linux systems (e.g., chmod 755). The […]
Everything about computers on the software level, programming level, etc., stems from this word. Binary means 0 and 1. It means whether the electrical signal is present or absent. In classical computers, these are the only two possibilities from which the entire digital world of information and computation emerges. Whenever you see a .bin file
The title of this article is in itself explanatory as to what is expected to be learned from this article. You must have seen that to denote the combination in mathematics or statistics, etc., as . This symbol means “the number of ways to choose ‘r’ objects from a total of ‘n’ objects. Let’s take
This is one of the very interesting topics, which can be used to learn and practice more about angles. Almost all of us wear watches and have clocks on the walls. A very simple circle, divided into 12 parts that give us the correct time, according to which we plan our daily tasks and maintain

In this short article, we will explore the idea of exponents a little further and see some important values of the exponents of the first ten natural numbers (1 to 10). This data can be used in probability theory for finding the sample space of multiple coins or dice thrown simultaneously. Powers of 2: Powers
In daily life, people often interchange the words ‘possibility’ and ‘probability’. However, these words are NOT interchangeable. “Possibility” is used when there is something that is said in qualitative terms (mostly as a vague statement). It is related to most of the tasks, which are assessed to determine whether or not they are possible to

I would like to dive straight into the concept of factorials. It is a simple mathematical operation used to find the total ways in which certain entities (numbers, people, objects, etc.) can be arranged in a straight line. All numerical factorials are represented by a number followed by an exclamation mark. $$ \text {For example,
Before jumping to this topic, you must make sure that you know how to handle percentages and calculate the values for various fractions and numbers in terms of percentage. Once done, this topic is really like its name. Simple. The most common scenario in simple interest is the percentage of return on the principal investment
This topic is pretty basic, but its applications are endless in real life. This very term (percentage) is used in countless comparisons, competitions, and evaluations. It is also used in experiments and applications of mathematical and physical laws in laboratories to measure accuracy or inaccuracy for drawing conclusions. The word percentage comes from the Latin
We know that multiplication of numbers can be visualized as repeated addition of the same number.For example, We can visualize 76 multiplied by 87 as the number ’76’ added 87 times to itself, or the number ’87’ added 76 times to itself. The numerical multiplication is therefore called ‘commutative‘ (a times b = b times
