Not in the way that you would do it in a spreasheet program.

You rill need to get the values from the table into variables and then operate
them.
To get a value from the table use:
getResult("Column", row)
Returns a measurement from the ImageJ results table or NaN if the specified
column is not found. The first argument specifies a column in the table. It must
be a "Results" window column label, such as "Area", "Mean" or "Circ.". The
second argument specifies the row, where 0<=row<nResults. nResults is a
predefined variable that contains the current measurement count. (Actually,
it's a built-in function with the "()" optional.) Omit the second argument and
the row defaults to nResults-1 (the last row in the results table). See also:
nResults, setResult, isNaN, getResultLabel.
