Resistor Calculator - Given the color bands on the resistor, it will tell you the resistance and tolerance rating. It is designed so that you may easily see how resistance is calculated using the color bands and hence calculate resistance on your own
The program TouchMaths (for touchscreen mobile phones) contain a set of revolutionary mathematical applications (Professional Calculator, Graph 2D, Function solver, Integral solver, Equation solver and Linear system solver)
EasyCalcBasic - A very simple calculator.
Enter a list of up to 10 numbers, add labels.
Comes with hyper-intelligence:
You can write *,x,/,div,divide,subtract,plus,minus,times,takeaway, or pls,tms,add...you will still get the same result
Calculator V1.02 - This is the calculator which has many functionalities than the normal calculator provided in the mobiles, this software is mainly designed for the touch screen mobiles. This will not work on the mobiles which do not have touch screen facility
Graphing Calculator - FREE app, designed to turn your cell phone into a Graphing Calculator.
It should work on all phones that support J2ME, like Nokia, Blackberry, Motorola, LG, Samsung, Sony Ericsson and more (specifically MIDP 2.0 and CLDC 1.1)
Graph2Go - Graphing calculators are instrumental in teaching and learning mathematics. It is an environment that supports conceptual understanding of functions in general, and school algebra and real analysis in particular. Especially, it enhances connections between graphic and symbolic representations
Solve2Go - supports solving equations and inequalities by means of conjectures based on visual thinking. Conjectures can be refuted or supported by examples provided by the tool, and should be proved using symbolic manipulations on paper.
Equations: when we want to know for which values of x the two functions are equal
