-31°F = °C -31+(-31)=-62 -62 + 33 = -35°C Answer: -35°C Correct?

Right.

Thanks!

You're welcome.

I'm sorry, but the conversion you have done is incorrect.

To convert from Fahrenheit (°F) to Celsius (°C), you can use the formula:

°C = (°F - 32) * 5/9

Let's calculate it correctly:

( -31 - 32) * 5/9 = (-63) * 5/9 = -35°C

So the correct conversion is -31°F is equal to -35°C.

You did the arithmetic incorrectly in your calculation. Remember that subtraction takes precedence over addition:

-31 + (-31) should be calculated as:

-31 + (-31) = -62

And then adding 33:

-62 + 33 = -29

So the result you obtained, -29°C, is not the correct conversion. The correct conversion is -35°C.
