Rachel solved 5 math problems each minute for 12 minutes before bed, but she didn't finish all of them. The next day, she finished the last 16 problems at lunch. How many math problems did she do in all? Let's be accurate as possible.
Before going to bed, Rachel did a total of 5 × 12 = 60 problems. In total Rachel did 60 + 16 = 76 maths problems.
The answer: 76.
