# I jump high or low?

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?

Binary XOR Operator(Symbol :- ^)

Solution:

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)

Explanation:

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.
