The quiz won the first prize, and the Olympics won the third prize; Very good. I didn't buy any materials in grade 5.6.

Can the four operations in the second volume of the fourth grade math exam in primary school solve simple calculations? We must use the basic algorithm of four operations to calculate, but we must use the methods of exchange and association law to make the calculation obviously simple. Death does not give points.
There is an urgent need to calculate 50 simple calculation problems in the fourth grade of primary school with simple methods.

Four arithmetic exercises in the fourth grade of primary school, book 2, it's half a month before I leave school today. The weather is particularly sunny. My mother said she would take me shopping. I jumped out of bed happily, dressed quickly and went to the food market with my mother. Wow! The vegetable market is really lively, full of people, selling and laughing. I saw round and red tomatoes like apples, thin and long bean sprouts, purple eggplant like a curved moon, lovely boats, and many green vegetables, lettuce, green vegetables, cabbage and so on. Listen to my mother: "Today, my uncle, uncle and aunt will come to my house to celebrate my upcoming school." So my mother and I bought a lot of vegetables, such as: bought two Jin of tomatoes, two yuan per Jin; I bought three Jin of wax gourd, one yuan per Jin; Long beans bought three Jin, two yuan per Jin; I bought two Jin of soybean sprouts, one yuan per Jin. At this moment, my mother asked me a question. Xinxin, you can use your math knowledge to calculate how much it will cost to buy food today. I smiled and told my mother that a * * * costs fifteen dollars. The formula is as follows: (2× 2)+(3×1)+(3× 2)+(2×1) =15 (yuan). My mother smiled and said to me, "Well, the answer is right." %D%A Supplement: %D%A I borrowed my sister's diary and copied it (she is also in the fourth grade) for reference! %D%A
