This afternoon, grandpa said that there were not many dishes at home and he was going to buy food. I shouted, "I'll go, so will I." In this way, grandpa and I set off.

At the vegetable market, we looked around and saw a tomato seller. I think those tomatoes are big and round, like the red face of a shy little girl. I quickly stopped grandpa and picked a few big and red ones. After weighing, my grandfather asked me to calculate the price of these tomatoes. A kilo of tomatoes 1.5 yuan,1* * 2.5kg. Can't you multiply them? But it's not easy to ride like this! After thinking for a while, I thought of a good way, that is, using the learned multiplication and division method, I first asked for two kilograms of 3 yuan, and then asked for 0.5 kilograms of 0.75 yuan, so I bought 2.5 kilograms1* * at 3.75 yuan. Hearing that I worked it out, grandpa said happily, "Yes, it seems that you have not learned mathematics in vain for so many years!" ''

Through this incident, I know that quick calculation is very close to our life, and I will study harder and be a little psychic in the future.
