     9|| - || unary || number || changes sign of argument ||
     10|| - || binary || number || subtraction ||
     11|| * || binary || number || multiplication ||
     12|| / || binary || number || division ||
     13|| % || binary || long || modulus ||
     14|| & || binary || long || bit-wise and ||
     15|| | || binary || long || bit-wise or ||
     16|| && || binary || boolean || logical and ||
