The difference between +30 and -13 is 43 degrees.
t- temperature in January T-temperature in April
Δ- difference beteween temperature
Δ=T-t Δ=30F-(-13F)=30F+13F=43F
The difference between the typical January temperature of -13°F and the typical April temperature of 30°F in Fairbanks, Alaska, is 43°F. This is calculated by adding 13°F to 30°F, since subtracting a negative temperature is equivalent to addition. Thus, the final answer is 43°F.
