Some people find number puzzles hard to resist. If you're one of this minority of the population then this is the ideal quiz for you. It tests the foundations of Mensa type number puzzle solving skills. I'm not an expert at time allocation but at a rough guess I would allow yourself a maximum of 15 minutes to complete this quiz.
In this quiz each numerical equation has question marks in it. You need to select the alternative in each case which replaces the question marks with the correct mathematical signs and makes the equation true. The signs used are +, -, x, and / . Some equations are just equated to a number but others contain missing numerical evaluations on both sides.
