Using the Expression Evaluator
The Scientific Expression Evaluator is used to obtain results from a complex or sim-
ple mathematical expression. It follows the operator hierarchy and algebraic gram-
mar rules. For example, in a standard calculator 2+2*3 would equal 12, but in an
algebraic calculator that same expression would equal 8. This is because in a stan-
dard calculator the expression is evaluated from left to right, but in an algebraic cal-
culator, calculations follow the rules of algebra (operator hierarchy takes priority). In
this particular case the first action would be multiplication and then addition. You
must also remember that bracketed expressions and powers are calculated before
anything else.
Operator Hierarchy:
1. Brackets
[()]
2. Power [
^]
3. Multiplication [
*],
Division
[/],
Remainder
[\]
4. Addition [
+]
and Subtraction
[-]
You can use all numbers [
0 to 9]
on the keyboard, as well as Other Valid Keys to
enter your expressions. You can also use up to three Variables
(X,Y & Z).
Enter your expression into the main Expression Readout box. (This is the box lo-
cated to the left of the
OK
button.) You can either type your expression or paste it
