Solve this sum. Get to the number 112 using only the numbers 1 through 6 and you can ONLY use four numbers. You also cannot repeat a number you have already used. You can also ONLY use multiplication. No addition, subtraction or division and you are not allowed to use notation either. Just multilying four numbers together. The amount of numbers used to achieve 112 also has to be four numbers exactly, not less or more than four.
