In this book, we are first going to learn to understand and then create algorithms. After that, we are going to learn how to program with Scratch 3.0. Inside, there are about a hundred algorithms and Scratch programs, displayed as examples or exercises with their correction, easily usable in classrooms or at home.
A common belief is that computers are very intelligent machines. That’s a complete lie, computers are very stupid and can’t do anything without their programmers and software creators. A computer, or a programmable calculator, isn’t able to understand something else than the specific instructions used as its language. Even a simple spelling error in the code makes it unable to work. It has no intuition, it simply can, often, tell the kind of error it encounters. But it is able to do repetitive tasks very quickly and without ever being fed up by them. If we ask it to count the number of the letter "e" in a text, even if it contains thousands of pages, it will do it precisely, quickly and perfectly.
That is why, to create a program, we have to write its structure: the algorithm, then translate the result into a computer language. There are many different computer languages. For calculators, it depends on their brand and type. For computers, it depends on their exploitation system and the type of software you want to create.
In this book, we are first going to learn to understand, then to write, algorithms, in order to internalize the logic useful for any kind of programming. Then, we’ll learn how to use Scratch for mathematics as a matter of priority.
