Then let me talk about the answer to the Olympic Games first. Page 1: (1)1+2+34-5+67-8+9 =100 (2) 98+7-65+4-3-21= 20?

Page 2: (1× 2+3+4+5-6-7+8) ÷ 9 =1? Page 3: 9+13× 7 =10014÷2-5 = 2.

Page 4: 1.653.854.5438+08? 2.535.06 17.6? Page 5: 6×9=54? 12+3-7=8

Page 6: Omit (figure 1) Page 7:19.99+9.99× 9 =10+9.99× 9 =10+9.99 (1 +000-3-4+8- 1=54500 Page 9: (I use * for multiplication symbols) (I use/represent division symbols) 9.9 * 9.9+0.99 = 9.9 * 9.9+9.9 * 0.1= 9.9. Page 10: (1) > (2) =? Page 1 1: Two people? Page 12: 1 1 Page 13 only: 5795.5795.5/5.795 * 579.5 = 5795.5795 * (579.5/5.795) = 5795.

Page 15: (Figure 2)? Page 16: (Figure 3) Page 17: (1)65536(2)262

Page 18: 75 kg 65 kg Page 19: 99? 36? 36? 100 100

Page 20: (1) 8888/8+888+8 * 8 = 2000 (2) (9 * 8 * 7-6-5+4+3) * 2 *1= 65438.

I only told page 20 because I was exhausted from typing. Please give me a reward! ) For the remaining pages and answers, please add me QQ: 56470 1 104.
