• To solve 3 : 8 = X : 12 for X, for example, press
in step 1, and
then input the following for the coefficients (A = 3, B = 8, D = 12):
3
8
12
.
• Pressing
will reset all of the coefficients to one.
4. After all the values are the way you want, press
.
• This displays the solution (value of X). Pressing
again will return
to the Coefficient Editor.
Important:
A Math ERROR will occur if you perform a calculation while 0 is
input for a coefficient.

Errors
The calculator will display an error message whenever an error occurs for
any reason during a calculation. While an error message is displayed, press
or
to return to the calculation screen. The cursor will be positioned
at the location where the error occurred, ready for input.
To clear the error message:
While an error message is displayed, press

Error Messages
Math ERROR
• The intermediate or final result of the calculation you are performing
exceeds the allowable calculation range.
• Your input exceeds the allowable input range (particularly when using
functions).
• The calculation you are performing contains an illegal mathematical
operation (such as division by zero).
→
Check the input values, reduce the number of digits, and try again.
→
When using independent memory or a variable as the argument of a
function, make sure that the memory or variable value is within the
allowable range for the function.
Stack ERROR
• The calculation you are performing has caused the capacity of the
numeric stack or the command stack to be exceeded.
→
Simplify the calculation expression so it does not exceed the capacity
of the stack.
→
Try splitting the calculation into two or more parts.
Syntax ERROR
• There is a problem with the format of the calculation you are performing.
Argument ERROR
• There is a problem with the argument of the calculation you are
performing.
