Identify Temperatures: Identify the temperatures recorded on each day and list them for comparison. $\newline$ Monday: $-8\degree F$ $\newline$ Tuesday: $-2\degree F$ $\newline$ Wednesday: $-30\degree F$ $\newline$ Thursday: $15\degree F$
Compare Temperatures: Compare the temperatures to determine which is the lowest. Remember that on the Fahrenheit scale, a lower number means a colder temperature, and negative numbers are colder than positive numbers. $\newline$ $-30^\circ\text{F} < -8^\circ\text{F} < -2^\circ\text{F} < 15^\circ\text{F}$
Identify Lowest Temperature: Identify the day with the lowest temperature from the comparison. $\newline$ The lowest temperature is $-30\degree F$ , which was recorded on Wednesday.
