Temperature difference 2

The temperature in London on new year’s day is -2 degree Celsius. The temperature in Moscow on the same day is -14 degree Celsius, what is the temperature difference between the two cities?

Correct result:

d =  12 °C

Solution:

t1=−2 ∘C t2=−14 ∘C  d=t1−t2=(−2)−(−14)=12∘Ct_{1}=-2 \ ^\circ \text{C} \ \\ t_{2}=-14 \ ^\circ \text{C} \ \\ \ \\ d=t_{1}-t_{2}=(-2)-(-14)=12 ^\circ \text{C}
