The temperature rose by 11 degrees Fahrenheit today. Write a signed number to represent this temperature change

The rise in temperature by 11 degrees Fahrenheit can be represented by the temperature change, ΔT = + 11 °F. The temperature change is positive because the temperature increased as stated in the question. Moreover, the formula for temperature change is: ΔT = T_final - T_initial. This means that for this case, the final temperature is higher than the initial temperature.
