For a blind student I'm making a excel-sheet working like a graphics-calculator table.

In Cel C10 I want to put the math-function using an "X".

In column A18 thru A38 there are some values for "X"

Then I want to display in column B18 thru B38 the calculated answers ... using the value for "X" in the neighbour cell.

For example in B18 I want to replace the "X" in the formula by the value in cell A18 ... and calculated.

How to do this?

Substitution is no problem, but I like to have it calculated ...

function
y=x^3+x+2-2^3+-2+2
startvalue x
-2-2

<colgroup><col><col span="2"><col></colgroup><tbody>
</tbody>

Can a formula spear through sheets?
Use =SUM(January:December!E7) to sum E7 on all of the sheets from January through December

Thank you for your answer ... but

that's what I particulary don't want to do.

It is for a blind student.

One stop, one go.


Working like TI-84 or the calculation sheet in Geogebra
