Yes that seems to be very basic calculation.
Today seems to be 7 degree Celsius and yesterday was 13 degree3 cooler.
Then the solution is 7-13= -6 degree Celsius.
Temperature seems to be the physical quantity which express cold and hot.
It is a proportional measure of average kinetic energy of random motion of constituent particles of matter in a system.

The temperature today is 7 degrees Celsius
⇒ Temperature today = 7ºC
Find the temperature yesterday:
Let the temperature yesterday be x
Yesterday was 13 degrees Celsius cooler than yesterday
⇒ It is cooler, therefore the temperature decreases
Solve x:
⇒ x = 6 - 13
⇒ x = -7ºC
Answer: The temperature yesterday was - 7ºC
