# Handwriting input

## Entering numbers

All Sanjütz input is a one-stroke input. Please note that the way to write “4” and “5” is different from normal numbers.

Basically, enter according to the stroke order (arrow direction) in the above figure. Some numbers can recognize different stroke orders. (Reverse rotation of “0”, etc.)

## Perform calculation

The calculation in Sanjütz is the same as a normal calculator. Enter a number, enter the symbols for calculation (“+” and “-“) in order, and finally enter “=”.

Sanjütz is calculated in input order. Operator precedence is not taken into account.
5 + 2 x 3 = 21 .. OK?
NOT 5 + 2 x 3 = 5 + (2 x 3) = 11. If you need such a priority, you have to calculate 2 x 3 + 5.

## Special operation

• Function
Display the function menu (can also be displayed with a digital crown)
• Memorry
Display the memory / history menu (can also be displayed with a digital crown)
• +/-
Inverts the sign of the displayed number
Example: 3 ← → -3
• Exp (Exponential)
Enter the “E” symbol for the factorial of 10
2.5 “E” 3 is equal to 2.5 x 103 (2500)
• Del (Delete)
Deletes the previous digit input by one digit. You cannot delete anything other than entering numbers (such as arithmetic operations)
• Clear
To erase a number in the middle of a calculation, use “C” in the function menu.
Or enter the decimal separator (“.”) twice in a row.
• ALL Clear
To erase everything, including calculation operations, use “AC” in the function menu.
Or enter the decimal separator (“.”) three times in a row.
