&lt;br /&gt;
== Description ==&lt;br /&gt;
&lt;br /&gt;
The arithmetic combinator is part of the [[Circuit Network]] and one of three types of combinators available in the game. It is used to &lt;br /&gt;
perform simple mathematical operations on signals, capable of addition, subtraction, multiplication, or division. The arithmetic combinator accepts two input connections (red and green wires), and sends it&#039;s output to both output connections. The input wires connect to the nubs on the left side of the above sprite, while the output is on the opposite side.&lt;br /&gt;
&lt;br /&gt;
==Function==&lt;br /&gt;
The internal logic process has three steps:&lt;br /&gt;
&lt;br /&gt;
1) All input signals on the red and green wires are summed within the combinator.&lt;br /&gt;
&lt;br /&gt;
2) The specified operation (+, -, *, or /) is performed on the selected signal(s).&lt;br /&gt;
&lt;br /&gt;
3) The result of this operation is output as the selected output signal.&lt;br /&gt;
&lt;br /&gt;
