The more the Chinese New Year comes, the more I feel a sense of panic and anxiety. I am afraid of my relatives' questions, I am afraid of my parents' endless urging to marry, and I am also afraid that the circle of friends is higher than low.
Today, I still wake up early at 6:30. To save some money, I bought a box of eggs (which cost 22 yuan) and plan to use this for breakfast in the future.
Many people have advised me not to focus too much time and energy on the quantitative relationship, which has a low score and is time-consuming in the exam room, so it is better to start with the three areas that are easy to score. Having listened to the persuasion, I decided to synchronize the quantitative relationship with the judgment and reasoning. From 7 o'clock until 11 o'clock, I listened to these two lessons**, and after sorting out and understanding the notes, it was time for lunch. A serving of hot and sour noodles and a bowl of eight-treasure porridge cost a total of 27 yuan.
After taking a nap until half past two in the afternoon, I got up and did a set of public exam questions. This was more than 3 hours until almost 6 o'clock, as if my speed could not keep up with the speed of time. This time it's a little bit better than last time, and I'm over the passing mark, so I hope I can keep up the good work.
Throw down the pen and go out and buy a birthday cake for myself, and wish myself a happy birthday! The birthday cake costs 26 yuan.
In the evening, I analyzed the mistakes and easy points in the past questions. I memorized the General Knowledge test points part of the past papers. This is the end of the fourth day of the examination. It cost a total of $75 today.

Remainder characteristics: 1. The basic concept of remainders.
If a b=q......r (a is called the dividend, b is called the divisor, q is called the quotient, r is called the remainder) a = bx q + r (dividend = divisor x quotient + remainder).
r2. Basic operations on remainders:
Remainder addition theorem: If a c = q1......r1，b÷c= q2……r2
Then the remainder of (a+ b) c is the remainder of (r1 + r2) c.
3. Congruence theorem:
The remainder is the same as the remainder, the sum of the same is the same, the difference is the same as the subtraction, and the least common multiple is the cycle.
Hypothetical proposition: 1) Sufficient conditions.
1. Definition: A is established, B is established (if there is A, there is B) - A is a sufficient condition for B.
2.Reasoning formula: Sufficient conditions are pushed forward and backward {front is after sufficient}
3.Logical words: (1) If a, then b—ab
2) As long as A, then B—Ab
3) If a, then b—ab
4) A is B-AB
5) A then b-ab
6) A must be b-ab
7) A is inseparable from B-AB
8) For A, B-AB
9) All A is B—AB
10) Everything a is b:—ab
2) Necessary conditions:
1. Definition: A is an indispensable condition for the establishment of B, and there is no B---without A
A is a necessary condition for B.
2.Reasoning formula: The necessary condition is pushed back and forward.
The front is the post; After the arrow is necessary}
3.Logical words: (1) Only a, only b—ba
2) a, only b—ba
3) Unless a, only b—ba
4) A is the premise of B's foundation prerequisite and necessary requirement.
5) Without A, there is no B—Ba
Without A, there is no B—Ba
6) Unless A, BFebruary** Dynamic Incentive Program
