My local pizzeria sells eight different kinds of pizzas: cheese, pepperoni, mushroom, alfredo, meat lover’s, vegetarian, Hawaiian, and deluxe. In how many ways can I order two pizzas for delivery, if I don’t mind whether I get the same or different kinds of pizzas? I'm confused pls help

You can order two pizzas 8 + 8*7 = 64 ways.
