Who is Numera for?
Virtually anyone can use Numera. However, it was designed for engineering and mathematical disciplines, people who have taken a programming class or two, and those who are interested in learning basic programming concepts and logic. We've also noticed that children ages 10 and above "catch on" very quickly.
At its most basic level, Numera can be used in place of a calculator. Let's look at an example.
Suppose you wanted to calculate the following expression:
sqrt( 3.45 + ((56.4 + 7.2**2.8) / 3.44) - 12.33 + (3 * (23.87 + 21.33 + 8.44)) )
Go ahead and try to enter that into a hand-held or even a computer based calculator. You'll then appreciate that in Numera you enter it in a wordprocessor-like environment (see below).
Here's what we've done in the example below on line 1:
1. We made a variable called: total
2. We ASSIGNED that long expression to total with the "=" assignment operator.
3. We ended the expression with a semicolon
Simply press the "Calculate Expressions" button and the result is displayed in the results box on the right.
That's all you need to know to start using Numera.
