As soon as I entered the door, I found grandma holding a spring scale in her hand, as if to weigh something. Curious, I immediately ran over, grabbed the spring scale and said loudly, "Grandma, let me help you weigh it!" " "
"no! You won't! " Grandma said incredulously.
"Don't worry, Grandma, I learned kilograms and grams!" As I spoke, I hooked a bag of vegetables and proudly said, "It's weighed, 1 gram!" Grandma smiled and said, "Who will eat 1 g food?" It turns out that I used kilograms as grams again. How careless!
I ran to my mother and asked her to weigh me. My mother smiled and squatted on the ground. It was a long time before she recovered her breath and said, "You weigh 25 kilograms. This spring can only weigh 4 kilograms at most. How can I call you? " She turned my face red and white.
Students, mathematics is used in many places in life. If you don't learn well, you will make jokes like me.
