For arithmetic calculation such as addition,subtraction etc we are using add,multiply & more tools from the Numeric palette.If many inputs are using in the calculation, the block diagram should be little bit extended by more Numeric tools & wiring. For a clean block diagram use Compound Arithmetic tool from numeric palette.By using this tool the addition & subtraction ,Multiplication & division calculations are easily accomplished without using the separate tools like Add, Subtract, Multiply, Divide.For example, Result=I1 + I2 –I3 calculation is done as per below (See Picture 1 for both two methods).
The invert terminal denotes the opposite calculation(In addition operation invert works as subtraction & Multiplication operation invert works as division ).To get invert input terminal- Right Click on the terminal and choose invert.Boolean operations is also done in that tool by changing its mode(By Right Click on the tool->Change mode->OR).
