# 01 - Computational Theory, thinking and logic

1. Computational thinking is the art of a human being able to think like a computer (e.g. in binary using 1s and 0s)

FALSE

TRUE

2. Computational thinking is a ….

way of computing things in binary and not the alphabet

way of thinking about a problem to understand it and then logically working out a good solution

way of computing big numbers and adding them up faster than a computer would

way of thinking with numbers as opposed to with words

3. There are generally speaking four elements of computational thinking. What are they?
```Elements of Computational Thinking
==================================
1. Decomposition
2. Pattern Recognition
3. Abstraction
4. Algorithmic Thinking
5. Binary number conversion
7. Subtraction```

1,3,5,7

1,4,5,6

1,2,3,4

3,4,5,6

4. Read the excerpt on computational thinking (from barefoot computing) and see if you agree.
```Exmaple of computational thinking
----------------------------------
For example, if you’re going to make an animation,
you need to start by planning the story and how you’ll
shoot it before you can use computer hardware and software
to help you get the work done.

The thinking that is undertaken before starting work on a
computer, breaking down the steps and truly understanding
the problem, is known as computational thinking.```

False

True

5. Computational thinking is not thinking about computers or like computers. Computers don’t think for themselves. Not yet, at least!

TRUE

FALSE

6. Why is computational thinking so important?
`Computer scientists are interested in finding the most ____________way to solve problems. They want to find the best solution that solves a problem correctly in the fastest way and using the least amount of resources (time / space)`

time consuming

efficient

tiring

7. Read the alternative definition of the stages in computational thinking and fill in the blanks
```Elements of Computational Thinking
==================================
Another characterization of computational thinking is an process
based on three stages

1 - A___________: Problem formulation (leaving out the irrelevant details);

2 - Automation: Solution expression;

3 - Analyses: Solution execution and evaluation```

abduction

abortion

abstraction

absailing

8. Two important parts of computational thinking are: 1. Logically organizing and analyzing data and 2…...

Taking the problem to combine it with other bigger problems

Breaking the problem down into smaller parts

Comparing the problem to all the other problems in the entire world

Breaking the problem into bigger problems and parts

9. Another definition of computational thinking is as follows: The ____________ involved in formulating and breaking down a problem and expressing its solution(s) in such a way that the steps can easily be followed to produce the solution

CPU logic

thought process

boolean gates

binary arithmetic

10. If you have the time, feel free to watch this educator's guide to computational thinking. What is Algorithm design?

There is no such thing

Developing binary arithmetic techniques to help the computer add up

Developing fast techniques to add two numbers together

Developing the step by step instructions for solving this and similar problems
