Math Help - Exor

I have a strange hw question. Find the origins of the symbol "EXOR", the plus sign with a circle around it. He hinted that it is Latin in origin, but I've been coming up with squat =(

Hello,

originally the sign is: XOR.

It's the abbreviation of eXcluding OR. (As you may know the connection of two values with OR ( $\vee$ is including)

The XOR-connection is mostly used in computer science to connect 2 bits:
XOR-connection of 2 Bits:
0 XOR 0 = 0
0 XOR 1 = 1
1 XOR 0 = 1
1 XOR 1 = 0

Read 1 = true and 0 = false.

The negated form of the XOR-connection is XNOR.

You'll probably find furthwer and detailed information in wikipedia.
