Inputting Expressions and Values
X Mark I Pro allows you to input a single calculation with up to 99
bytes. When input capacity is less than 10bytes, the input cursor
will change from "
" to "
" signaling that the memory is running
New Input begins on the left of display. When the input data is more
than 15 characters (Line Mode) / 16 characters (Maths mode), the
line will scroll to the right consecutively. You can scroll back to the left
to review the input.
Omit the multiplication sign and final close parenthesis.
Example: 2 x log 100 x (1+3) = 16 .......
*1. Omit multiplication sign (x)
- Input before an open parentheses
- Input before scientific functions that includes parenthesis: 2 x
- Input before Random number function
- Input before Variable (A, B, C, D, X, Y, M), π, θ
*2. Scientific functions come with the open parenthesis. Example: sin(,
cos(, Pol(, LCM(.... You need to input the argument and the close
*3. Omit the last close parenthesis before the
: 1 x (2+3)

function that needs to be deleted, then press
In Overwrite mode: Move the cursor under the character or
function being deleted, then press
