The teacher sent us the math test paper for us to read carefully. After the teacher read it, we all started to do it. The classroom is very quiet, only the rustling sound of writing can be heard. I did this problem carefully and finished it in a short time. Look at other students, some are looking around, some are biting their pens. They must be in trouble. I checked the test questions carefully and the bell rang. I handed the test paper to the teacher happily.
I thought, "I have to get a hundred points today." This math problem is really simple!
