During a History class, the 7th grade students learned about the extreme temperatures faced by explorers on their polar expeditions. During an expedition to the South Pole, a group of explorers recorded a temperature of -23 degrees Celsius in the morning. Throughout the day, the temperature dropped even further, reaching a mark that was three times the morning temperature in absolute value. However, in the evening, there was an improvement, and the temperature rose by 15 degrees Celsius. What was the temperature at the South Pole at the end of the day, after the improvement in the evening? Explain the reasoning used to arrive at your answer.
