Welcome to the puzzle section of Sensenwerk.
Most of the 'enigmas' here need some mathematic strategy to solve, but some could easily be done by an 8-year old. Just have fun and don't let them get to you. ;-)

Use the numbers 1,3, 4, 6 only ocnce (but you must use each). You may add, subtract, divide and multiply and use brackets () as often as you like. The goal is to get the result 24.
No tricks, just pure mathematics.
