Types of Scientific Calculators

Depending on the scientific calculator class, you will be able to solve small or large variations of complex problems. Apart from scientific calculators which can be used to solved complex problems, there are graphic calculators for those in the finance and statistics field.

Scientific Calculators
Their design allows the user to quickly access mathematical functions more precisely. As standardized maths assessments gain popularity globally, these calculators are becoming a basic requirement. The user can input a whole equation and get a final answer.

Graphing Calculators
This goes a step further than a basic scientific calculator. If you constantly need to complete simultaneous equations, perform variables and other tasks, and plot graphs, these offer you the best solutions. Being highly customizable, they are best equipped to handle advanced mathematics. The display is larger to accommodate graphs and codes.

Financial Calculators
Similar in design and function to standard calculators, financial calculators feature shortcuts and quick-access keys around financial requirements. Just as graphic calculators, they are customizable to performing specific functions.


Shopping for the best scientific or graphing calculator is never a walk in the park. One must ensure the calculator’s functions and capabilities will serve all their needs. Texas Instruments TI-84 Plus stands out as a graphing calculator that easily performs other scientific functions as well.
