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?
A-) Yes, Antonio is correct
B-) No. The answer should have been 9 degree, not -9 degree because a negative plus a negative is always positive
C-) No. Antonio should have subtracted -5 - (-4) because the temperature dropped.
A-) Yes, Antonio is correct
