What Is the Desmos Scientific Calculator?
Desmos is a web-based mathematical calculator for both computational and graphing purpose which is very different to traditional calculators which primarily focus on computation rather than how the result will visually appear when plotted on standard Cartesian coordinate system (i.e. what’s happening inside an equation as you type).
A very important advantage of using the visual aspect of Desmos is that it provides an opportunity for users to:
a. Establish relationships between their variables
b. Witness changes in the function being manipulated as that manipulator changes; and,
c. Become more comfortable understanding all mathematics by making both computations and graphing less troublesome.
Desmos is regularly used in educational facilities at every level, from elementary education through graduate-level education, but it is also a popular choice among independent learners, self-taught individuals, and professionals seeking efficient and accurate computational solutions.

How Desmos Scientific Calculator Helps with Learning
Math education presents the challenge of knowing the “why” behind each feature. Desmos takes care of this through clear visualizations of outputs.
For example:
When a coefficient is altered, the graph will either grow larger or smaller; and
When adjusting any constants, it will shift the graph vertically and/or horizontally;
When multiple equations are plotted together on a single graph, it will indicate general properties (from a visual point of view) relative to the original graphical output created by using only the algebraic formulas.
