Basic Operations

To turn on the TI-36X Solar, expose the solar panel to light and press !. Note: Always press ! to clear the calculator because memory and display may contain incorrect numbers. To turn off the TI-36X Solar, cover the solar panel with the slide case.
( selects the 2nd function of the next key pressed. " selects the 3rd function of the next key pressed.
Third function Second function Primary function
For example, 8 " finds the cube root of 8. To cancel 2nd or 3rd, press ( or " again.

Results

The TI-36X Solar calculates up to 12 digits and can display up to 10 digits plus a minus sign (-9,999,999,999 through 9,999,999,999) and a 2-digit exponent. Results with more than 10 digits display in scientific notation.

Number-System Modes

" Selects decimal mode. " Selects binary (BIN) mode and converts the integer portion of the displayed number. You can enter positive binary numbers as large as 111111111 (9 digits). Numbers beyond this are interpreted as negative (2s complement) numbers. " Selects octal (OCT) mode and converts the integer portion of the displayed number. You can enter positive octal numbers as large as 3777777777. Numbers beyond this are interpreted as negative (2s complement) numbers. " Selects hexadecimal (DEC) mode and converts the integer portion of the displayed number. You can enter positive hexadecimal numbers as large as 2540BE3FF. Numbers from FDABF41C01 through FFFFFFFFFF are interpreted as negative (2s complement) numbers. Note: Hexadecimal numbers between 2540BE3FF and FDABF41C01 are equivalent to decimal values that are outside the range of the calculator and therefore cause an error.

Boolean Logic Operations

You can perform logical AND, OR, XOR, XNOR, and NOT operations in the decimal, binary, octal, and hexadecimal modes. Except for NOT, these functions compare the corresponding bits of two values. The result is displayed in the current number base. Note: Although the TI-36X Solar does not display leading zeros for integers, logical operations treat each value as a 10-digit binary number. (A displayed value of 0, for example, is treated as 0000000000 BIN, and a displayed value of 1 is treated as 0000000001 BIN.) Keep this in mind if you see unexpected results.

AND OR XOR XNOR NOT 0 AND 0 = OR 0 = XOR 0 = XNOR 0 = 1 NOT 0 = AND 1 = OR 1 = XOR 1 = XNOR 1 = 0 NOT 1 = AND 1 = OR 1 = XOR 1 = XNOR 1 = 1
