Perform simple mathematical operations on attributes with single channels.
First - connect an attribute as the first operand.
Operation - select the mathematical operation to apply.
Second - connect an attribute as the second operand.
Result - the result of your operation (read only - use the ID as the output)
Math outputs a single channel so can be used to connect to other single channels. For attributes like Position which have two channels [x,y] use a Math2.
