1)Data entry.

2)Process.

3)Data output.

Operations to be used:

Sum:                  +   a+b  7+3= 10

Subtration:                  -   a-b   7-3= 4

Multiplication:   *   a*b   10*2= 20

División:              /   a/b   12/2= 5

Mod:                    mod   a mod b   10 mod 2= 0

Div:                      div   a div b   10 div 2= 5

                 15 mod 2= 1       15∟2

                 15 div 2= 7           1丨7.5

                 15/2= 7.5

Operator hierarchy:

1. ( )

2. √{[n]1/2 Potency{** ^}       From left to right→

3. * /  mod div                            All operations

4. + -

 Fractions of Sum  :

a) a/b+m/b= a+m/b= n/b

b) a/b+m/n= a*n+b*m/b*n= c/o

Relational Operators:

They are symbols that are used to compare two values, if the result of the comparison is correct, the considered expression is true, otherwise it is false.

   5<4  False

 5>4  True

   5<=5  True

5>=6  False

"Hola"=="hola"   False

6!=6  False

Logic operators:

They are used to combine two Boolean values and return a true,false or null result, logical operators are also called Boleans

V O V  V     V Y V  V

          V O F V     V Y F  F         

F O V V    F Y V  F

Exercise:

Shoe on the screen a tittle that says mathematical operations, enter 2 integers by keyboard, generate an output with the answer for a sum.

FinAlgoritmo

Según:

The segun works so that when the user enters number or option they are directed to the select option and executesthe assigned operation.

Repetitive cycles:

Para:It is used to ask from which variable to which variable you want to know. 

Mientras:An action is performed and then the user is asked if  they want to repeat the action or not.
