Introduction to Maths

Gaining relevant, useful knowledge and applying it helps us build confidence to navigate the world around us in a bold way. Either it be career or personal life, knowledge is required to perform one’s duties and contribute better toward society as a whole. One such branch of knowledge is Mathematics

Mathematics or Maths is the branch of knowledge that deals with numbers, quantities, shapes, patterns and logical arrangements or relationships.

It helps us to make sense of the world using calculations and reasoning.

Interesting Maths Facts

Here are some interesting facts about Maths:

Zero was discovered in India
The concept of zero was developed by Indian mathematicians. Without zero, modern mathematics and computers would not be possible.
The word “Mathematics” comes from Greek
It comes from the Greek word mathema, which means “knowledge” or “learning.”
Every even number greater than 2 may be written as the sum of two prime numbers
Example:
10 = 5 + 5
20 = 7 + 13
This is called Goldbach’s Conjecture, but it has not been fully proved yet.
Pi never ends
The value of π is approximately 3.14, but its decimal digits go on forever without repeating.
A circle has infinite lines of symmetry
No matter how you divide a circle through its centre, both parts are equal.
The number 9 has a magical property
If you multiply 9 by any number and add the digits of the answer, the result often comes back to 9.
Example:
9 × 7 = 63
6 + 3 = 9
One is not a prime number
A prime number has exactly two factors: 1 and itself.
Since 1 has only one factor, it is not prime.
Maths is used in nature
Patterns like honeycombs, flowers, shells, leaves, and even pineapples follow mathematical patterns.
There is no Roman numeral for zero
Ancient Romans did not have a symbol for zero in their number system.
The Fibonacci sequence appears in nature
The sequence 1, 1, 2, 3, 5, 8, 13… appears in sunflower seeds, pine cones, shells, and flower petals.
A triangle is the strongest shape
Triangles are used in bridges, towers, and buildings because they are very stable.
Maths helps improve logical thinking
Solving maths problems trains the brain to think step by step and find solutions.
The equals sign was invented in 1557
It was introduced because writing “is equal to” again and again was too long.
Every number has a square, but not every number has a perfect square root
Example:
5² = 25, but √5 is not a whole number.
Maths is the language of science
Physics, chemistry, astronomy, engineering, coding, architecture, and economics all use mathematics.

Introductory Video on Maths

Below is an introductory video on Maths. Watch it to know where it is used and broad topics in Maths

Why learning Maths is important?

Imagine going to a grocery store and there is a balance amount to be paid by store owner and you don’t know arithmetic of what needs to be paid by him ! Cringe situation, right?

Learning and applying Maths in daily life improves brain power and helps make intellect sharp as it helps develop logical thinking, improve problem solving skills and also the ability to use careful examination in order to understand or explain something. This skill is also essential in careers, to name a few, like engineering, science, research, teacher, data analyst.
