문제

Little Mirko wrote into his math notebook an equation containing three positive integers, the equals sign and one of the four basic arithmetic operations (addition, subtraction, multiplication and division). During another class, his friend Slavko erased the equals sign and the operations from Mirko's notebook. Help Mirko by reconstructing the equation from the three integers.
