Learn Math Tutorials. The word math stands for mathematics. It is a field of study. The word mathematics originates from the Greek word máthema. The meaning of máthema word is science, knowledge or learning. Both math and maths are short forms of mathematics. So, the word mathematics is the same as math. These short words often used by students and their schools for arithmetic, geometry, and algebra.
Commonly, there is no accepted definition of math. Aristotle defined mathematics as, the science of quantity. The definition given by Aristotle prevailed until the 18th century.
The study of numbers, shapes, and patterns is called math. In other words, we can define the term math as, the field of study that uses numbers and symbols for measurement, properties, relationships of quantities, and sets.
According to the German philosophers Carl Friedrich Gauss, mathematics is the Queen of the Sciences.
Modern philosophers do not consider mathematics as a science because science is based on empirical observations and seek to understand some aspect of phenomena. While math defines the relationship between quantities and objects and seeks to use logic to understand. The mathematics do not relate to any phenomena.
The study of math includes the following:
Numbers: The study of numbers involves how can we count the things.
Structure: The study of structures involves how things can be organized. The subfield of structure is called algebra.
Place: The study of place involves the arrangements for the things. The subfield of place is called geometry.
Change: The study of change involves how things become different. The subfield of change is called analysis.
Why math is important?
Math is very important in our daily lives. In reality, it is implemented everywhere. It is useful for solving problems that occur in the real world. This is the reason that so many people besides mathematicians study and use mathematics. There are too many fields such as natural science, engineering, medicine, finance, etc. that uses mathematics.
There are the following reasons that makes the mathematics as a powerful tool.
Math is involved around us. So, it is an essential and powerful discipline in today's world. Our perspective of the important issues facing us as individuals, families, businesses, and nations.
It provides an effective way of building mental discipline.
It improves mental rigor for developing logical, analytical, and problem-solving skills.
The knowledge of mathematics plays a crucial role in understanding other subjects such as physics, art, music, etc.

PEMDAS is an acronym that is taught in school classrooms across the nation. It helps students remember the priority, or Order of Operations, used to solve expressions involving strings of numbers and operators. It stands for:
P(arenthesis)
E(xponent)
M(ultiplication)
D(ivision)
A(ddition)
S(ubtraction)
A familiar mnemonic widely used in place of PEMDAS is: Please Excuse My Dear Aunt Sally. Thus the name of this application... Kind of an inside joke for the mathematical types.
Computers, including smart phone calculators, desktops, etc. have built in functionality to properly interpret such expressions so we don't have to. But have you ever wondered what algorithms the CPU executes to get the right answer every time? This app demonstrates one such algorithm called the Shunt Yard, developed a few years back by Professor Edsger W. Dijkstra.
We’re going to take a closer look under the hood at Order of Operations algorithms. It will interest programmers and school students alike; for programmers, the use of queues and stacks will reinforce previous computer science learning; for students, it allows them to write an expression, then analyze it using Order of Operations rules, step by step. The Quiz mode generates random expressions of user selected lengths and magnitudes and checks the student's answer. Incorrect answers can be examined using the same step by step process.
In the SOLVE mode, algebraic expressions are entered free hand using an internal keyboard which limits entries to the five common mathematical operators (+ - / * ^) as well as one level of parenthesis. There is a maximum term limit of ten variables, but no limit to their magnitude in this mode.
In the QUIZ mode, between two and ten variables can be selected, their maximum value and which operators that are eligible. The program then randomly generates an algebraic expression using these parameters.
Both modes make available an analysis page which is used to step through the solution. Stack/Queue dynamics are displayed.
