It is basic math to understand that both the operations are different forms of multiplication. You may even use factorial notation, which is a group of multiplications.
However, our target can be achieved with the help of an unary operation in computer science. Express 7 as a binary number, i.e, 111 and perform left shift binary operation resulting in 110, i.e, number 6 in decimal system!
