Doing Math in Qbasic:

Try this:

PRINT  8 + 12

Qbasic handles all math functions, be careful with the order you do things in.

PRINT  (134 + 589)/45

Variables:
      Variables are a very important and powerful part of programming. A variable is a 
word or letter that represents a place where Qbasic keeps some information for you.

Try this:

a = 1
PRINT a

When you typed in "a = 1", Qbasic stored the number 1 in memory and you told it to call 
this place "a" ( "a" is the variable).   When you typed in "PRINT a", your computer 
displayed the number that was stored at "a" and this was the number 1.

Input:

   This is a very handy command that allows the computer user to store numbers or words 
as variables.

Try this.

INPUT "Enter a number",n
INPUT "Enter a number",x
CLS
PRINT "The first  number is";n
PRINT "The second number is";x

The program stores any number you enter as the variables "n" and "x".
