Arithmetic, Relational & Logical Operators

Computational Thinking

Operator

Is an expression that allows us to make arithmetic, relational or logic operations.

ArithmeticOperators

Are those that uses mathematical operations to obtain real numbers.

**

Different types of divisions: result = 10 / 6 , result = 1.67result = 10 // 6, result = 1result = 10 % 6, result = 4

Relational Operators

> Greater than

== Equal

< Lower than

!= Not equal

>= Greater or equal

Are those that compares two values in order to have a boolean (true or false) value.

<= Lower or equal

Relational Operators

Logical Operators

Are those that evaluates two expressions in order to have a boolean (true or false) result.

Logical Operators

Lets try it!

PRECEDENCE

NOT

OR

NOT

AND

(4^2+10)*5-64 =

18<64 AND NOT 23>54

6>8 OR NOT 100<200

5-2<5^0 OR 10*2>5*2

5^2>6*4 AND 40-4<7*5

Conditional Structure

It means that you have another way to go through a solution. In other words, is like giving another ending to a story.

What is a condition?

Is a decision-making based on a possibility.

Calculating the volume of a sphere.

Algorithm: Step 1. Start Step 2. Get the radius value in variable rarius. Step 3. Save the value of the constant Π in the pi constant. Step 4. Calculate the volume of the sphere with the following formula: volume = 4/3Πr^3 Step 5. Show the volume obtained. Step 6. End
