Mathematics

Introduction Mathematics deals with two kinds of quantities such as constant quantities or constants as well as variable quantities or variables. However, when the value of the quantity remains the same under the varied situations, then it is said to be constant. On the other hand, when the value of the quantity differs under varied […]

The word trigonometry has been derived from the Greek word trigonon meaning triangle and metron which means to measure. Trigonometry is considered the most ancient subject among all. It has been studied by several scholars around the world. The ratio of the side length of the triangle is known as the trigonometric ratio. The ratios

What are Decimals? A lot of ancient civilisations, including the Harappan, Greeks, Romans, and the Egyptians, used a system of numerals called the decimal. Even the Vedas are said to have this system of numbering. It is said that since humans have 10 fingers, the decimal numbering system uses multiples of 10. Decimals can also

Omar Khayyam, a Persian mathematician, and Chia Hsien, a Chinese mathematician, discovered the triangle thousands of years ago. The triangle is also described in a Saint Emmeram document from the 10th century that is well preserved at the Monaco library. Pascal, a French mathematician, is credited with inventing a variety of triangle kinds, features, and

The ratio is a relationship or comparison between data, quantities, amounts, etc. It is used to compare quantities; it can be anything – length, volume, area, amount, height, side, etc. There are several types of ratios.  There is another term, proportion, when two ratios are set equal to one another in an equation, then it

Quantifying things is a crucial part of our daily life. We have to count everything around us almost every day. Since we deal with numbers very frequently, it’s essential that we know the types of numbers that exist. The most common types of numbers discussed in mathematics are natural numbers and whole numbers. While they

A number is a sign that denotes a quantity. There are three different kinds of numbers; real numbers, imaginary numbers, and complex numbers. Real numbers are simple numbers that can be quantified and identified like 8, -9, 4, etc. Imaginary numbers are the ones that are easy to imagine but cannot be perceived in reality

What is the perfect number? A perfect number is a number whose sum of the factors excluding itself is equal to that number or we can say that the number whose sum of all the factors is equal to the multiple of 2 of that particular number. For example; 6, the factors of 6 are

What are the Co-prime numbers? Co-prime numbers are also known as relative prime numbers or mutually prime numbers. It is defined as the numbers which have 1 as their greatest common divisor or highest common factor. It is the prime number that divides only one number and cannot divide the other number. For example; 7

Numbers are defined as mathematical identities that measure, count, or label items. Egyptians were the first to invent the number system. The Roman number system, a unique combination of Roman alphabets, was popular in Europe until the 14th century. Thereafter, the Hindu-Arabic number system was invented and is widely used to date. This number system
