1. Introduction
To make a problem is like make a trip. To make a trip, first we need to know where we want to go. If we do not know it, we will never take the right road. On a trip we use the car, bus, train, plane or other means.
To make a problem, we have to know well what it asks or what we have to obtain. For that, we use additions, subtractions, multiplications, divisions or other operations.
To make problems, we need two things: first, we must know how to do the operations (addition, subtraction, multiplication, division and other operations) and second, we must understand what the problem asks, that is, we have to know where we want to go. If we do not understand what we need to obtain, we will never solve the problem. We can say that we understand a problem when we express what the problem asks with other personal words, other than the statement.
In the problem there are three different parts: a) what the problem asks, the unknown quantity, b) what the statement says, the information of the problem, c) the solution that is achieved after making the correct operations.
Example: I have seven candies (information) and someone gives me 3 candies for my birthday (information). How many candies do I have now? (unknown quantity). After making the sum of 7 and 3, we know that I have 10 candies (solution).
