The solution is displayed next to the variable for which you solved.
A solid square in the first column marks the variable for which you
solved and indicates that the equation is balanced. An ellipsis
shows that the value continues beyond the screen.
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 the exponent.
