Math is a real challenge for many. Admittedly, calculus takes some training, but simple tasks such as addition and subtraction may ocassionally be just too much. Percentages are another major obstacle. I meet almost daily statements that you can save as much as 5%, 10% or even 20% by some irresistible deal. The other day Ryanair provided yet another example. They promised me to save over 20% buying six scratch cards for €10 when one card was sold for €2. What’s wrong you might say? Well, €2 off from €12 is not over 20%. It’s less — only 16,7%. So are Ryanair cheating or just poor at math?
