S To delete a function
Example To delete the contents of function memory number 1
*(E)(E)(FMEM)*
(STO)@U
* fx-7400G
II: (FMEM)
• Executing the store operation while the display is blank deletes the function in the function
memory you specify.
I Answer Function
The Answer Function automatically stores the last result you calculated by pressing
U (unless the U key operation results in an error). The result is stored in the answer
memory.
• The largest value that the answer memory can hold is 15 digits for the mantissa and 2 digits
for the exponent.
• Answer memory contents are not cleared when you press the key or when you switch
power off.
S To use the contents of the answer memory in a calculation
Example 123 + 456 = 579
789 – 579 = 210

• The answer memory contents are not changed by an operation that assigns values to Alpha
memory (such as: D??J(B)U).

• In the Math input/output mode, the operation to recall answer memory contents is different
from the operation in the Linear input/output mode. For details, see “History Function” (page
1-17).
• Performing an operation that assigns a value to an Alpha memory (such as
D??J(B)U), answer memory contents are updated in the Math input/output mode
but not in the Linear input/output mode.
