One minus one is not zero. (type a word), answer: three.
Seven eighths. (To use an idiom), the answer: seven ups and eight downs.
Second, interesting questions.
Puccio is a famous mathematician in the former Soviet Union. 195 1 wrote a book, Math Teaching Methods in Primary Schools. There is an interesting question in this book.
This shop sold 1026 meter cloth in three days. The sales volume of the second day is twice that of the first day; On the third day, it sold three times as much as the next day. How much rice cloth do you want to sell in three days?
The first day 1 serving; The second day is twice as much as the first day; The third grade is three times that of the second grade, and the first grade is 2×3 times. Comprehensive calculation shows the number of meters of cloth sold on the first day:
1026÷(L+2+6)= 1026÷9 = 1 14(m)
And 1 14×2=228 (m).
228× 3 = 684m
So the fabrics sold in three days are: 1 14m, 228m and 684m respectively.
