Problem
4. The temperature in Chicago is \( -7^{\circ} \mathrm{F} \) and the temperature in Milwaukee is \( -13^{\circ} \mathrm{F} \). Explain your reasoning. How much lower is the temperature in Milwaukee than the temperature in Chicago? Explain your reasoning in the show your work section. 6 degrees 7 degrees 21 degrees 5 degrees
Solution
Step 1 ：Subtract the temperature in Chicago from the temperature in Milwaukee: \( (-13) - (-7) = -13 + 7 \)
Step 2 ：Evaluate the expression: \( -6 \)
Step 3 ：The temperature in Milwaukee is \( 6^{\circ} \mathrm{F} \) lower than the temperature in Chicago.
