Enter numerical calculations as you would text in a word-processor, so that you can edit and review your entire formula.  Then, save it to file and add notes to it so that, you when you use in future, you know how it works.

Use named variables in your calculations, for example Income=GrossIncome-Tax.  You can declare and use as many variable as you wish and their names may be as long as you like. Variables are managed in a separate pane of the Calculator, so you never need to remember which variables you have declared.

Evaluate unknown variables in equations: just place a question mark where you want the Calculator to evaluate the variable, for example 3.5=1x5.7*?, and the Calculator will work out the value needed to satisfy the equation.

Insert physical constants in your calculations from the Calculator's library of constants data.
Convert values from imperial to SI units: the Calculator has a library of over 100 conversion factors.

Run iterative calculations.  For example, suppose you want to calculate compound interest over, say, 10 years.  Your formula could be entered in the Calculator like this:  Growth=Growth*AnnualInterest.  All you then need to do is click the Calculator's 'Iterate' button and enter a starting value for 'Growth' and the number year you want to calculate for in the dialogue that the Calculator displays.

Save your calculations to a named file, together with the variables they use and any associated notes you have made: the Syberad Calculator comes with over twenty financial and scientific functions of its own which you can use and edit. 

Plot graphs from coordinate data you either enter or load from file.  The data can presented as either a cartesian line plot (ie. a standard graph) or as a bar-chart.  In either case, plot colours and settings are fully customizable.

Add error-bars to your data:  you can specify values for each coordinate or use a generic function.

Add a regression line-fit to your data: linear, logarithmic, reciprocal, gaussian, hyperbolic, parabolic and cubic spline fitting functions are supported.

Plot functions such as y=sin(x).  You can enter any function for plotting, it can be as complicated as you like.  Functions can also be set in motion (animated in real-time) so that you can visualize them as a wave-form.

Chart axes are fully customizable so that you can make a chart look exactly the way you want.

Combine charts to produce multiple curve plots.

Add text labels to your charts: these can be moved to any location on in the chart.

Pan and zoom your chart so that you can control exactly which part of an extended data set is visible on the chart's axes.

Save and load charts to and from a file.

Print charts using either the Calculator's internal print-engine or copy them to other applications such as Microsoft Word and Powerpoint.

Calculate the mean, standard deviation and correlation coefficient for a plotted data set.

Calculate the mean, mode, median, standard deviation and confidence interval for a data set.

Save statistics calculations to a file and print them.
