Tātaihia te -4 mā te pū o 2, kia riro ko 16.

$$\sqrt{16}=|-4|\text{ and }|-4|=4$$

Tātaitia te pūtakerua o 16 kia tae ki 4.

$$4=|-4|\text{ and }|-4|=4$$

Ko te uara pū o tētahi tau tūturu a ko a ina a\geq 0, ko -a rānei ina a<0. Ko te uara pū o -4 ko 4.

$$4=4\text{ and }|-4|=4$$

Whakatauritea te 4 me te 4.

$$\text{true}\text{ and }|-4|=4$$

Ko te uara pū o tētahi tau tūturu a ko a ina a\geq 0, ko -a rānei ina a<0. Ko te uara pū o -4 ko 4.

$$\text{true}\text{ and }4=4$$

Whakatauritea te 4 me te 4.

$$\text{true}\text{ and }\text{true}$$

Ko te kōmititanga tōrunga o \text{true} me \text{true} ko \text{true}.
