Given,
Temperature outside = -35°C.
Temperature inside = -10°C.
Difference of temperature can be calculated by subtracting the temperature outside from the temperature inside.
An important tip to be noted here is that:
●
![( - ) - ( - ) = ( - ) + ( - ) - ( - ) = ( - ) +](https://tex.z-dn.net/?f=+%28+-+%29+-+%28+-+%29+%3D++%28+-+%29++%2B+)
This means that while finding the difference between 2 negative numbers = 1st number + additive inverse of 2nd number.
So,
(-35°C) - (-10°C)
= -35 + (10)
= -35 + 10
●While adding a positive and a negative number we subtract it and place the sign of the greater number.
= -(35-10)
= -25°C.
Therefore, the difference in temperature in the hotel I. Greenland is -25℃.
