Ngā Upane Otinga

Whakareatia te 6 ki te 7, ka 42.

$$\left(-\frac{42+3}{7}\right)\times \frac{2\times 2+1}{2}$$

Tāpirihia te 42 ki te 3, ka 45.

$$-\frac{45}{7}\times \frac{2\times 2+1}{2}$$

Whakareatia te 2 ki te 2, ka 4.

$$-\frac{45}{7}\times \frac{4+1}{2}$$

Tāpirihia te 4 ki te 1, ka 5.

$$-\frac{45}{7}\times \frac{5}{2}$$

Me whakarea te -\frac{45}{7} ki te \frac{5}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-45\times 5}{7\times 2}$$

Mahia ngā whakarea i roto i te hautanga \frac{-45\times 5}{7\times 2}.

$$\frac{-225}{14}$$

Ka taea te hautanga \frac{-225}{14} te tuhi anō ko -\frac{225}{14} mā te tango i te tohu tōraro.

$$-\frac{225}{14}$$

Tauwehe

$$-\frac{225}{14} = -16\frac{1}{14} = -16.071428571428573$$
