E 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
too many functions and/or parentheses. If this
happens, divide the calculation into multiple parts
and calculate each part separately.

«When you press (=) 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 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 /
