Oh, dude, it's like adding fractions at a math party. So, one and two thirds plus one and two thirds equals... drumroll... four! Yep, that's right, four! So, if you've got one pizza with two-thirds eaten, and your friend brings another pizza with two-thirds eaten, you've got a full pizza party with four-thirds of pizza left!
