Equation

Displays the currently defined

equation.

Equation Variables

Displays all equation variables and

their values.

Default={M1©99,1©99}

Displays the 

 limits that apply to

the unknown variable value for which

you are solving.

You select one variable, the one you

want to solve for, from this list.

 

The first line of the Equation Variables screen displays the

equation you defined on the 

 screen.

If you would like to edit a defined equation, press $ until the

 screen is displayed. Edit the equation with

:, /, or - m, as necessary. Then press b to

return to the Equation Variables screen.

 

All variables included in the defined equation are displayed. If

those variables have never been assigned a value, they are set

equal to 0. If a variable has been defined previously (for

example, from the Home screen), that value appears.
If a value extends beyond the screen, press " to scroll to the

end of the number. This is especially important if a number is

in scientific notation and you need to see whether it has a

negative or positive exponent.
For an equation with more than one variable, you must define

all variables except the unknown variable for which you want

to solve.
