We've barely started exploring our solar system when a message is received from outer space.
It looks like an encoded operation is embedded in the message. And it also looks as it is a test of some sort.
4 *&* 8 = 6 20 *&* 5 = 12 8 *&* 31 = 34 ------------- 44 *&* 47 = ?Maybe we ought to respond to it?
What do you think?
P.S. General rules are the same as in Mystery OP I and Mystery OP II
