  • why do you remove the negative sign? I don't get it

  • @wendysuck In the end the negative sign is removed for convenience and hopefully ease of understanding. The PED is always "negative" but often the sign is removed so we can easily compare PED at different levels. This makes it easier (hopefully) then if PED less than 1 it is inelastic and greater than 1 PED is elastic. It may be confusing if there were negative signs too.
