5. Move the cursor to the variable for which you want to
solve and press ƒ [
The solution is displayed next to the variable for
which you solved. A solid square in the first column

Note: When a number continues beyond the screen, be sure to
press ~ to scroll to the end of the number to see whether it
ends with a negative or positive exponent. A very small number
may appear to be a large number until you scroll right to see
