TI-83 Plus Math, Angle, and Test Operations 76
The default guess is calculated as (upper+lower)
2.
4. Edit bound={lower,upper}. lower and upper are the bounds between which
the TI-83 Plus searches for a solution. This is optional, but it may help
find the solution more quickly. The default is bound={L1å99,1å99}.
5. Move the cursor to the variable for which you want to solve and press
ƒ \ (above the Í key).
• 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.
• The values of the variables are updated in memory.
