How to adjust all the items in a list with a formula in Inflex

Open up Inflex.

  1. Hit the List button.
  2. Hit the + button to add a row.
  3. Hit the yellow box to put in a number.
  4. Type in 123 and hit Enter.
  5. Repeat adding a couple more rows of numbers: 456, 789.
  6. Click the (unnamed) bit of the box and type in list and hit Enter, so we’re naming the cell “list”.

Now we can manipulate it:

  1. Hit the Formula button to make another cell.
  2. In the new cell’s white box, type li and when the word list appears, press Enter (or on your tablet, tap it).
  3. Then type the period key: .
  4. Now type map and you’ll see map appear. Hit Enter again.
  5. Write () which, like in Excel, means “here come some inputs”.
  6. Type the following in between ( and ): x:x*2 and then hit Enter.
  7. You should see a new list that is all the things in the first list multiplied by 2.

You now know how to change the items in a list with a formula.
