monday (circ) tuesday (circ) wednesday (circ) thursday (circ)

Explanation:

Step1: Recall temperature comparison rules

For positive and negative temperatures, positive values are warmer than negative ones, and among negative numbers, the one with the smaller absolute value is warmer (closer to zero). The temperatures are: Monday: \(0^\circ\text{F}\), Tuesday: \(-18^\circ\text{F}\), Wednesday: \(-12^\circ\text{F}\), Thursday: \(-30^\circ\text{F}\).

Step2: Compare the temperatures

Compare \(0\), \(-18\), \(-12\), \(-30\). Since \(0\) is greater than all negative numbers (\(0 > -12 > -18 > -30\)), Monday's temperature is the highest.

Answer:

Monday
