When both are the same, I jump low.
When both are different, I jump high.
You can use me to add, but I don't know maths.
What am I?
The answer is
Binary XOR Operator(Symbol :- ^)
If we call the inputs A and B and the output C we can show the XOR function as:A B C 0 XOR 0 -> 0 0 XOR 1 -> 1 1 XOR 0 -> 1 1 XOR 1 -> 0
Weighing scales (not the digital ones)
When both sides have the same weight, the scale's bar remains low. When the 2 sides have different weight, it tilts and one side jumps high.
