So the other evening at dinner I asked my son what he was studying in math. He told me he was doing decimals and Star Wars numbers.
"Star Wars numbers?" I asked, "What do you mean?"
"You know," he said, "like Star Wars Eye and Star Wars Ivy. I can count to 1000."
"Oh, gotcha. Star Wars I, and Star Wars IV," I said, "Yes, those are important to learn."
PS) It's also notable that Star Wars math has it's limitations, other than just missing a 'zero.' For instance Star Wars II + Star Wars III does not equal Star Wars V. Just ask my wife.
