The Jinx Calculator To help you find out if this puzzle will work for all numbers, we will use a special spreadsheet “calculator." Here's what your Jinx Calculator will look when you open it. Notice that 6 was the chosen number and entered in cell B1. The spreadsheet then
quickly did all the calculations and the answer was once
again 13 - the unlucky number. Can you find a number that
will make the puzzle not end in 13 (and not jinx you?) Use
the Excel version of the Jinx
Calculator to help you. (Hint: Try
different kinds of numbers not just whole
numbers. Like these: 2.5, -56, 3000, 999999999,
.000005. Fractions can also be tried. For example if
you try 1/2, you enter =1/2 into the cell. Share
a
few
of your interesting examples of numbers that you used
here. Go
to
the results
page and describe the results. Questions: Is it possible to try all numbers on the spreadsheet? If not, what are some numbers we can't use in a spreadsheet? |
