U ovoj lekciji naučiti ćemo kvadrirati. Kvadriranje je operacija u kojoj broj množimo samim sobom, „a na kvadrat, jednako, a puta a”. Kvadrat negativnog broja je uvijek pozitivan broj, iz razloga što je: – × – = + (minus puta minus jednako plus). Kod kvadriranja razlomaka, kvadriramo posebno brojnik posebno nazivnik.
