Answer:
If 0 degree Celsius = 32 degrees Fahrenheit, why can’t we say that 0 degree Celsius + 0 degree Celsius = 64 degrees Fahrenheit?

Temperatures can’t be added.
This is an example of the concept of , and I advise reading the Wikipedia page, as I cannot reproduce it in full here.
I will say that temperature is measured on the interval level. You can’t add temperatures, just like you can’t add the names “Meni” and “Mike” (names are on the nominal level), and you can’t add the dates “August 1 2020” and “April 1 2019” (dates are also on the interval level).
You can add a temperature and a *temperature interval*. You can add a temperature of 32F with a temperature interval of 32F, and get a temperature of 64F. On the Celsius scale, the same calculation would be - add a temperature of 0C (equivalent to a temperature of 32F), with a temperature interval of 17.78C (euivalent to a temperature interval of 32F), getting a temperature of 17.78C, which is equivalent to a temperature of 64F.
Note that temperatures and temperature intervals are not the same thing. To convert a Celsius temperature to Farenheit you multiply by 1.8 and add 32; to convert a Celsius temperature interval to Farenheit, you just multiply by 1.8. A temperature of 32F is equivalent to a temperature of 0C, but a temperature interval of 32F is equivalent to 17.78C.
Temperature intervals, by the way, are on a ratio scale. They can be added, their ratio can be taken, and they can be multiplied by a number. (Not by another temperature interval! You would get something with dimensions of temperature squared, which is a completely different thing.)
You can also take a weighted average of temperatures. You can say that (2/3)*30C + (1/3)*10C = 23.33C. In Farenheit, the same calculation is (2/3)*86F + (1/3)*50F = 74F. And sure enough, a temperature of 74F is the same as a temperature of 23.33C. But the weights must have a total of 1, otherwise the calculation is meaningless.
This changes if we’re talking about temperatures on the Kelvin scale. That scale is measured against an objective, absolute 0 (unlike Celsius and Farenheit which have a relative, arbitrary 0), so temperatures and temperature intervals are the same, and can be added freely.
If I add 0 degrees Celsius to 0 degrees Celsius, does that make it 64 degrees Fahrenheit?
If 0 Celsius is 32F, is 0 Celsius + 0 Celsius 64F?
How come 25 degrees Celsius does not equal 53 degrees Fahrenheit?
Why aren't 0 degrees equivalent in Celsius and Fahrenheit?
If it is 0 degrees Celsius, what will that be in Fahrenheit?
If 0 degree Celsius = 32 degrees Fahrenheit, why can’t we say that 0 degree Celsius + 0 degree Celsius = 64 degrees Fahrenheit?
Six answers posted before this one. A few posters, notably and , have helpfully proposed analogies to show that adding two temperatures together is not “a thing.” Alas, the other four answers are not helpful for a variety of reasons.
If the analogies have not worked for you, the following probably won’t either. But maybe for others who arrive here to learn …. ?
Temperature is an intensive property. Which means that it doesn’t depend on the quantity present. The temperature of a certain quantity of water does not depend on the quantity. You can measure it with a thermometer, and the value will not change if you pour out half of the water. Intensive properties cannot be added together.
Some other intensive properties are boiling point, density, and hardness. Let’s use density as an example. If we have 200 mL of water, which has a density of 1.0 g/mL, and we pour an additional 200 mL of water into the container, is the density now 2.0 g/mL? (HINT: No.)
But the volume will now be 400 mL. Because volume is an extensive property, which mea
