Xiao Bei said to Xiao Lei, "Can you spell a number greater than 3 and less than 4 with three matches?" After a while, Xiao Lei smiled and said to Xiao Bei, "Come out!" , XiaoBei nodded after watching. Can you guess the number and the idiom?

(~3. 14, no three no four)

2. Guess the age

Someone asked how old Uncle Zhang was and how many months his grandson was born. Uncle Zhang wrote the word "Jing". Do you know their age?

(88 12 months)

3, longevity geometry:

Flowers bloom again, plus 37 years;

Qing ancient road is sparse, and there is one more spring and autumn in it.

(14 1 year)

4. Three links:

Committed to protecting Shu Han, writing a model,

Three things, four things,

Five road withdrawal, six road out of Qishan.

Seven capture Meng Huo, eight. ...

(eight defeats)

5, talk about the object:

W: If you want to ask me my last name, it's not Zhang or Li. It happens to be a math problem, and the number is equal to one plus one.

Man: What a coincidence! My family name is two plus one.

Woman: You asked me how old I am. Divided by 4 is greater than 3, divided by 2 is greater than 1, divided by 6 is greater than 5, divided by 8 is greater than 7.

M: You multiply 10, and I subtract 7, which is exactly 2 10.

(Female surname Wang, 23 years old; Male surnamed Tian, 27 years old)

6. Ironic riddle:

A woodcarving body, eyes wide open, three meals of tea and rice are not enough, limbs are weak, five internal organs are incomplete, six relatives deny it, know nothing, and eight sides are prestige, nine (long) has become famous, and ten (real) is useless.

(Clay Bodhisattva)

(1). One plus one is not two. The answer is "Wang".

Explanation: Combine the word "one", the plus sign "+"with another word "one" to get the word "Wang" instead of "two". Therefore, the answer is "Wang".

(2) One minus one is not zero. The answer is "three".

Explanation: The word "one", minus sign "-"and another word "one" are combined to get the word "three" instead of "zero". So, the answer is "three".

(3) You expect me, and I expect you. The answer is "equality".

Explain: "You are expecting me", you are waiting for me; "I am looking forward to you", I am waiting for you. Two people waiting for each other is "equality". So, the answer is "equality".

(4). Seven six five four three two one. The answer is "reciprocity".

Interpretation: The usual number of newspaper reports is from small to large, just like the popular song "One two three four five six seven, where is my friend". Now we say "765432 1", which is the reciprocal from the largest to the smallest, so the answer is "reciprocal".

(5). Seven eighths. The answer is "seven ups and eight downs".

Explanation: "Eight-sevenths" is written in mathematical symbols, with the number 7 written above the fractional line and 8 written below the fractional line. The answer is the idiom "seven ups and eight downs".
