It means this: So you need to do this:
 Can’t Simplify   Fraction simplification was attempted 
using the 'Simp function (page 
2-25), but simplification could not be 
performed using the specified divisor. 
  Example: Specifying a divisor of 3 to 
simplify the fraction 4/8. 
 Specify a different divisor or execute 
 'Simp without specifying any divisor. 
 Can’t Solve! 
Adjust initial 
value or 
bounds. Then 
try again 
 A Solve calculation could not obtain a 
solution within the specified range. 
 • Change the specified range.
  • Correct the input expression. 
 Time Out   A Solve calculation was unable to 
satisfy convergence conditions. 
 If you are performing a Solve 
calculation, try changing to the initial 
default estimated value. 
 Conversion 
ERROR 
 • Attempting to use the unit conversion 
command to convert between two 
units in different categories.
  • Executing a conversion calculation

conversion expression. 
 In a conversion expression, specify 
two different commands that are in 
the same category. 
 Invalid Type   An illegal data type is specified.   Specify valid data. 
Underflow When performing a function calculation 
or an equation calculation, you input 
an extremely small value for one of 
the arguments or you input values for 
multiple arguments that are extremely 
removed from each other.
Example: ∑(X,X,1,2,1E–50), 
1
E
99x
2
+1
E
99x+1
E
–99=0, etc.
Depending on the calculation 
contents, the underflow will occur and 
the calculation will not be performed. 
Change the value(s) and try again.
