Mixing Celsius and Fahrenheit

Add up three temperatures:

5°F +6°F +0°C

Correct answer:

t₁ =  43 °F
t₂ =  -11.6667 °C

Step-by-step explanation:

$$\begin{gathered} (F-32)\cdot {\displaystyle \frac{5}{9}}=C \\ {t}_1=5+6+(0\cdot {\displaystyle \frac{9}{5}}+32)=43^{\circ }\text{F} \end{gathered}$$

$t_2=(5+6-32)\cdot {\displaystyle \frac{5}{9}}+0=-11.6667^{\circ }\text{C}$

Hi
The above solution is incorrect as 0 degree Celsius is 32 degree Fahrenheit. Hence, the answer is 5 degree F + 6 degree F + 32 degree F = 43 degree F

Thank you
