Hey there! :)
If the temperature was at -41 F then warmed by 52 F, then what is our current temperature?
Simply do -41+52. Another way that your mind can do this is by rearranging this to look like this : 52 - 41
Because we are already very accustomed to doing this, we know that 52-41 is equal to 11. Therefore, -41+52 is very simply 11.
This means that our current temperature is 11 degrees Fahrenheit.
Hope this helped! :)
