Get to know your calculator. And your calculations.
Explore financial, scientific and graphing calculators in one beautifully focused workspace. Follow the keys, revisit a step and discover what changes when you try a different approach.
What makes it useful
Build confidence in the keys and the reasoning.
Explore the financial what-if
Enter a structured financial scenario. Change a rate, payment or term and understand how it affects the answer.
See another side of the problem
Inspect different representations. Move between calculation and graph to connect the procedure with the relationship it describes.
Financial, scientific and graphing
Change an expression. See the relationship.
A graph gives the calculation another dimension. Move from entering an expression to exploring its shape, then return to the financial or scientific instrument when the problem calls for it.
Useful alone. Better together.
Give the result somewhere useful to go.
Keep the method with your notes and bring the calculation into the workbook where you use it.
