We continue to combine the skills in elementary mathematics and its logical load, with creativity always present.

Also, an exercise in intelligent, creative and ethical thinking, caused by a controversy between Rafael and Antonio.

Let's go in parts.

Yo

Read the statement and the questions carefully.

The seemingly obvious is not always the right path.

Your friend Leonor Pérez has 8 children, each son has two sisters;

and she has 14 granddaughters, all female.

a.

How many children does Eleanor have?

b.

What is the name of the person who is friends with Leonor?

c.

What surnames do Leonor's granddaughters have?

d.

What makes you think of your friend's name?

and.

The two daughters only had two births each.

How did 14 girls give birth?

You must explain your answers.

We have a PICE exercise, based on a controversy between the brothers Rafael and Antonio, who had not appeared in our Column for a while.

Both passed through a park where there were two posters with these thoughts of two famous people.

Give me six hours to chop down a tree, and I'll spend the first four hours sharpening the axe.

When I am presented with a problem, I dedicate 80% of the time to interpreting it correctly, and 20% to solving it.

Rafael says that these thoughts have a high connection, while Antonio says that they have almost nothing in common.

What would you say to these brothers?

PICE stands for Thinking Intelligently, Creatively and Ethically

Remember that:

“An insignificant solution from your own head is preferable;

than a great one copied from the Internet or from another, especially without understanding it”.
