Math diary, a fourth-grade student with 200 words.

Today, the weather is very good. I discussed with my parents about going to the supermarket to buy things.

When I arrived at the supermarket, a dazzling array of things were in front of me, so rich! My parents and I wandered around, stirring up trouble. We bought 4 bags of potato chips, 2.99 yuan each, 5 bags of yogurt, 1.8 yuan one, 2 bags of biscuits, 4 yuan one, a bag of tomato sauce, 7 yuan, 1 catty of pork belly, 15 yuan, some Nestle crispy sharks, 22 yuan, and a bag of bitter is sweet, 3 yuan.

After shopping, it's time to pay at the cashier. My father asked me to calculate how much it would cost. At the same time, my father is also calculating. After a long three minutes, I said, "1 10.96 yuan!" Dad said, "Congratulations, you got it right!" "

Hearing my father's praise, I can't help feeling smug and having fun with math!
