Notes:
•
When defining a variable that you want to retain, use more than one character in the
name. This prevents it from being deleted inadvertently by
1:Clear a–z
.
•
For information about checking and resetting memory or other system defaults, refer
to
Memory and Variable Management
.
Single-character variable names are often used in
symbolic calculations such as:
solve(a
¦
x
2
+b
¦
x+c=0,x)
If any of the variables have already been assigned a
value, your calculation may produce misleading results.
To prevent this, you can select
1:Clear a–z
before
beginning the calculation.
