	~~The internal logic process has three steps:~~		The operands can be any single signal or a constant value. Up to one of the operands can be the [[Virtual signals#Each\|''each'' virtual signal]]. For each signal operand, the input wires can be selected. If both wires are selected, the inputs are summed.

	~~# All input signals on the red and green wires are summed within the combinator.~~
	~~# The specified operation is performed on the selected signal(s).~~
	~~# The result of this operation is output as the selected output signal.~~

	The operands can be any single signal or a constant value. Up to one of the operands can be the [[Virtual signals#Each\|''each'' virtual signal]].

	If neither operand is the ''each'' signal, the output must be a single signal. The operation is performed on the values of the chosen left and right signals, and the result is sent to the output on the specified signal.		If neither operand is the ''each'' signal, the output must be a single signal. The operation is performed on the values of the chosen left and right signals, and the result is sent to the output on the specified signal.

	'''Bit shift right''' and '''Bit shift left''' deal with numbers in the [[:Wikipedia:Binary_number\|binary]] representation. The 0's and 1's that make up a number are shifted in the specified direction which can result in a completely different number, due to the change in the binary value. The shift performed is called arithmetic shift, because it preserves the sign bit on bit shift right.
