If you are an advanced maths learner, you may have learnt about trigonometry (trig.), Pythagorean theorem, statistics, algebra, differential equations, equivalent fractions, geometry, probability, Scientific notation and other important mathematical concepts in the maths curriculum.
While mathematics can be overwhelming, it can also become fun math. It’s always important to remember the journey that you have taken with maths. In kindergarten, you would have struggled with basic math like Addition and subtraction, multiplication and division. In the primary grade math classroom, you may have struggled with a curriculum of times tables, adding and subtracting
In the early years of high school math, you may have struggled with arithmetic, calculus, graphing, sequences, fractions and algebraic math concepts.
Now you may be struggling with something else in your mathematics education, but like all of the times before if you focus and dedicate yourself. You will be able to grasp the new math concepts too. You may need to ask your math teacher for extra math help so that you can solve the math problem, or hire a tutor. Perhaps you can add some fun into your math learning and homework with math worksheets, quizzes, puzzles or math videos.
The good thing about math skills is that no matter how hard it appears if you reinforce your knowledge with lots of math practice and learning fun, you can understand any of the mathematical concepts introduced to you. This will lead you on to the road of mathematician mastery.
As you know math is intricately made up of so many kinds of number systems; whole numbers, negative numbers, symbols, decimal points, Exponent numbers, infinite numbers and much more. You may know special numbers like Some of these special numbers are seen with Euler’s e, the extraordinary number i, and of course the golden ratio.
But what about Pi? Let’s learn more about this special mathematical model

Pi is represented by the Greek letter π, The letter π was chosen from the Greek name περίμετρος which means perimeter. The definition that everyone probably knows is that the number Pi is defined as the ratio between the circumference ( c) of a circle and its diameter (d). c/d=pi
All circles are similar, and it is enough to know the relationship of similarity to move from one circle to another. Pi is about equal to 3.1416, or it can be rounded up to 3.14; however, researchers and mathematicians have found more than 12 trillion decimal places of Pi. Don’t worry you don’t have to learn them all.
Pi has been studied for thousands of years. The Egyptians and Babylonians are known to have investigated pi first estimating that pi was 3.125. It is amazing that they were so close given that there were no calculators, computers or the internet to help them to solve the equation.
In 220bc Archimedes the Greek mathematician set about to find out to measure pi accurately. He started his experiments by putting a square inside of a circle and a square outside of the circle. Doing some cool math, he got a range of number which gave him an estimation for pi. He then changed the squares for pentagons, and the number range got smaller and closer to pi. Then he replaced the pentagons with hexagons to get an even more precise estimation. He kept increasing the number of faces until he got to a 96 faced shape which got him to 2 decimal accuracy (3.14). This method has coined the method of exhaustion for obvious reasons.
Pi remains a mystery for scientists and fascinates professionals and amateurs alike who try to find out more about this number. Even today, research is being conducted to learn more about the Pi number.

Pi is not just about distracting students who are studying college algebra in math class to learn ever more challenging formulas to pass their Math exams or just to use algebraic formulas to calculate the perimeter, area and volume of a circle.
The number Pi has been used since antiquity by mathematicians, first to solve geometric problems, then in integral calculus and finally in the computation to calculate higher and higher decimals of Pi.
Geometry formulas involving Pi relate to circles and spheres.
Pi can be used to calculate:
And also volumes:
Probability and statistics involving pi relates to the law of Cauchy and in the normal law of expectation and standard deviation.
Pi can be used to calculate:
Other uses of the number Pi
The number Pi is also used in mathematics formulas with:
The list could go on.
The memorization of the number Pi becomes an obsession for many people.

If you want to try reciting a pi up to a maximum of 15 decimals, then you can try these short poems. The number of letters of each word corresponds to a decimal in the pi sequence:
This gives you a total of the first 15 digits of pi, which is as easy to remember as telling time! If you want to learn how to recite 75 digits check out this other blog post where the poem is laid out for you. However even with 15 digits you can impress your friend, they probably won’t think that you are mathematically gifted. But it’s a nice fun math poem that you can sure with your math tutor and people on your math course.
You never learn or retain more knowledge than when you are having fun. Everyone enjoys something and if you can incorporate interactive math, with a math game, jigsaw or logic game like sudoku.
You can also adopt a new way to study math:
Following the math curriculum for your grade level can be very useful to make sure that you don’t fall behind. But memorizing square roots and core standards isn’t going to get you all the way. Don’t let math problems discourage you, have fun with maths because there really is no limit to its possibilities.
