To study its interface, you can run it by clicking the Start button on the taskbar, then go to Programs, then Accessories. You should at least support the basic functions of addition, subtraction, and multiplication, as well as changing the sign of the number (the +/- key). It's up to you if you want to support the sqrt, %, and 1/x functions. Don't bother with the "M" keys on the left (MC, MR, MS, M+) or the scientific features.</span><br>

For example, a flower is loaded  certain color, shape and fragrance. Similarly programming  objects are loaded with properties. A property is a named attribute of a programming  object. Properties define the characteristics of an object such as Size, Color  etc. or sometimes the way in which it behaves. For example, a TextBox accepts  properties such as Enabled, Font, MultiLine, Text, Visible, Width, etc.</div><div style="text-align: justify;"></div>

In a sense, these controls are more similar to forms than  to other controls. For example, PictureBox controls support all the properties  related to graphic output, including AutoRedraw, ClipControls, HasDC, FontTransparent,  CurrentX, CurrentY, and all the Drawxxxx, Fillxxxx, and Scalexxxx properties.  PictureBox controls also support all graphic methods, such as Cls, PSet, Point,  Line, and Circle and conversion methods, such as ScaleX, ScaleY, TextWidth, and  TextHeight. In other words, all the techniques that I described for forms can  also be used for PictureBox controls (and therefore won't be covered again in  this section).</div><div style="text-align: justify;"></div>
