■ Displaying the Location of an Error
If an error message (like " Math ERROR" or "Syntax
ERROR") appears when you press 0 , press 0) or.
(0 This will display the part of the calculation where
the error occurred, with the cursor positioned at the
error location. You can then make necessary
corrections.
Example ;when you input 14 h -0 x 2= by mistake
instead of 14-^10 x2=
Use the insert mode for the following operation.
LINEI
You can also exit the error screen by pressing | a S
which clears the calculation.
Inputting with Math Format
When inputting with Math format, you can input and
display fractions and some functions using the same
format as they appear in your textbook.
Important!
Certain types of expressions can cause the height
of a calculation formula to be greater than one
display line. The maximum allowable height of a
calculation formula is two display screens (31 dots
X2) Further input will become impossible if the
height of the calculation you are inputting exceeds
the allowable limit.
Nesting of functions and parentheses is allowed.
Further input will become impossible if you nest
too many functions and/or parentheses. It this
happens, divide the calculation into multiple parts
and calculate each part separately.

•When you press 0 and obtain a calculation result
using Math format, part of the expression you input
can be cut off as shown in the Example 3 screen shot.
If you need to view the entire input expression again.
Press I
a S and then press ® .
Incorporating a Value into a Function
When using Math format, you can incorporate part
of an input expression (a value, an expression within
parentheses, etc.) into a function.
Example: To incorporate the expression inside of
the parentheses of 1 +(2+3)+4 into the.7~
function
iMATH
This incorporates the expression in
the parentheses into the function ■r
