Looking at it, I suddenly saw a cleverly planned topic in lecture 25. It made me never understand its meaning. After Xiao Min's mother killed the fish, Xiao Min helped her cook the fish. It took her 2 minutes to wash the fish, 2 minutes to cut the fish, 1 minute to cut the ginger slices, 2 minutes to wash the pot and 5 minutes to heat the oil. Can you arrange fish cooking reasonably and skillfully, at least for a few minutes?
I thought about it, but I couldn't figure out what it meant. At this time, my mother is cooking fish, and I am watching her cook fish. Looking at my mother's skillful movements, oh, I suddenly realized: "By the way, can you wash the fish while burning oil, cut the fish and cut the ginger slices?" After my efforts, I finally know the answer!
2+5=7 (minutes) The answer is at least 7 minutes.
After doing this math problem well, I understood the meaning of the sentence "Many things grind". Learning mathematics requires not only a clever brain, but also endurance and careful observation.
