In science class, Victor started an experiment using a solution with a temperature of -5°C. During the experiment, the change in the solution's temperature was -4°C. What was the final temperature of Victor's solution? To solve the problem, Antonio added -5 + (–4) and came up with an answer of –9°C. Is Antonio correct? Why or why not?
