Pancake Math

panecake2“Archaeological evidence suggests that pancakes are probably the earliest and most widespread cereal food eaten in prehistoric societies.” – Wikipedia


What is the maximum number of sections into which a pancake may be divided into by four straight cuts through it?

Here more difficult questions go:

1) Is it possible to divided it so that all sections have equal area?

2) How many pancakes are needed to reach your height if they are squeezed by the weight of the upper pancakes?

3) If I spent 30 grams of batter for a pancake (French-style crêpe) of 30 cm in diameter how much batter do I need for the square pancake of the same thickness and the side length of 30 cm?  


These and many other practical “pancake” questions are presented in the Applied Math section of A+Click series, which already includes more than 4500 questions.


Geek’s Questions: The Art of Asking Yourself

A+Click contributor Gerry Geek just published a new true story: Image

A group of friends visit me. They eat and drink everything, even the cat’s food, and then leave. The fridge is empty – only a glass of milk is left. I give half of the milk to my cat Ben. He drinks half of it and then I drink half of what is left. Again, he drinks half of what is left and then I do the same. We continue until nothing is left. What proportion of the initial amount of milk did I drink in total?

I remember the moment when I saw Jane for the first time. We were sitting at the same table at a tea room along with Mary and John. We looked at each other and I was sure that everybody immediately chooses another. If two boys and two girls choose a partner, then what is the probability that everybody chooses the person who chooses them?

Before I met Jane I had a relationship with three girls who lived in the same house. I sent three letters to them. If the postman put the letters into three different boxes without looking at the name of the recipient, what would be the probability that all girls received their letters?

An IQ Test that does not disappoint

What is the main problem with different IQ tests?Image

They are stupidly boring!

Most of them are based on specific types of questions. If you don’t know them, you are blocked and frustrated. If you know the specific types of questions, you can solve many of them.

Is it possible to balance objectivity and entertainment?

The A+Click team believes that the solution is diversifying the questions and adapting them to the tester’s ability. We have thus created a free IQ Test that:

1)    Includes more than 400 types of questions;

2)    Adapts to the age of the tester and his or her ability during the test; and

3)    Shows progress, even during testing.
