Since it is a square vegetable plot, if the land area required for each cabbage is 1 square meter, then this year's area minus last year's area is 211 square meters.
Then the square of the side length of this year's vegetable garden minus the square of last year's side length is 211, and according to the square difference theorem of x squared - y square = (x + y) * (x - y) , we get x + y) * (x - y) = 211
This is only true in the case of 1*211 and 211*1 (because integers are required), so x and y are 106 and 105 respectively
11,236 this year (106 squared), last year 11,025 (105 squared) 106 squared - 105 squared = 211
-
11,236 this year (106 squared) and last year 11,025 (105 squared).
106 squared - 105 squared = 211
-
It depends on how he plants and what he plants!
Growing vegetables should also pay attention to sparse density! Also, if he didn't grow cabbage and cabbage, how could he harvest cabbage?
-
This year's harvest can be added to last year's harvest of 211.

Very good. There are seven levels of IQ: IQ value greater than 140 is genius; Intelligence between 120-140 is excellent; Excellent intelligence between 110-120; average intelligence between 90-110 (most people); Low intelligence between 80-90; And between 70-80 is somewhat intellectually deficient; Finally, those less than 70 are considered imbecile.
The global average IQ level is from high to low: East Asians (105), Europeans (100), Southeast Asians (87), Native American Indians (87), Pacific Islanders Aborigines (85), South Asians to North Africans (84), South North African Black (67), Australian Aborigines (62).
GradingPsychology uses the "intelligence quotient" or "IQ" to indicate a person's level of intelligence. The usual algorithm for IQ is "mental age chronological age 100". After research and division, the level of intelligence can be divided into 7 levels.
1. An IQ value greater than 140 is a genius;
2. Very good intelligence between 120-140;
3. Excellent intelligence between 110-120;
4. Average intelligence between 90-110 (most people);
low intelligence between 90;
6. And between 70-80 there are some mental deficiencies;
7. In the end, those less than 70 belong to imbecile (this is not a curse, it is an academic term).

High IQ "IQ 133 falls under the category of "High IQ". At the beginning of the 20th century, the French psychologist Binet and his students compiled the world's first set of intelligence scales, and the IQ of normal people, according to this set of intelligence scale tests, is mostly between 85 and 115, so the IQ of 133 belongs to high IQ. ”

<> IQ above 130 belongs to the high-IQ group. The proportion of high IQ in the population (1,000 people): IQ is 120-129, there are 100 people (10%), IQ, that is, intelligence quotient (intelligencequotient), is an index of personal intelligence test scores compared with the scores of subjects of the same age, and is a measure of the level of individual intelligence.
The concept of IQ was proposed by Professor Terman, a psychologist at Stanford University in the United States.
Intelligence refers to the general mental abilities of living beings. It refers to a person's ability to recognize and understand objective things and use knowledge and experience to solve problems, including memory, observation, imagination, thinking, judgment, etc. This ability includes the following:
Ability to understand, judge, solve problems, think abstractly, express ideas, and speak and learn. When considering animal intelligence, the definition of "intelligence" can also be summarized as: the ability to adapt effectively to one's environment by changing oneself, changing one's environment, or finding a new one.
Intelligence, also known as intelligence, is the ability of people to recognize objective things and use knowledge to solve practical problems. Intelligence includes many aspects, such as observation, memory, imagination, analytical judgment, thinking, adaptability, etc. The level of intelligence is usually expressed by the intelligence quotient, which is used to indicate the level of intellectual development.
In particular, it should be pointed out that intelligence does not refer to wisdom, and there is a certain difference in the meaning of the two.

An IQ of 12 belongs to people with relatively high intelligence.
IQ is a 2-point scale, with 7 below being mentally retarded, 7 8 being low, 8 9 being lower-middle, 9 11 being normal, 11 12 being upper-middle, and 12 13 being upper. Reaching 13 is supernormal, and reaching 14 is basically considered a genius. Many aspects such as observation, memory, analytical judgment, thinking skills, adaptability, and reasoning skills.

An IQ of 120 is excellent. IQ, i.e., Intelligence Quotient.
Invented by the Frenchman Binet, it includes observation, memory, imagination, analytical judgment, thinking, adaptability, etc. It is people's ability to recognize objective things and apply knowledge to solve practical problems. The level of intelligence is usually expressed in terms of the intelligence quotient, which is used to indicate the level of intellectual development.
IQ Rating:A normal person's IQ is between 80 and 120, where 80 90 is lower-middle, 90 110 is normal, and 110 120 is upper-middle. 70 80 is low, below 70 is mentally retarded, 120 130 is superior, 130 is supernormal, and 140 is basically a genius.
Generally speaking, people with a relatively high IQ have the ability to learn.
It's stronger, but it's not necessarily a positive correlation between the two.

The number of people with an IQ above 130 is troubled by people with high IQs. The proportion of people with high IQ in the population (in units of 1,000 people): 100 people (10%) with an IQ of 120-129, 25 people with an IQ of 140-149 (IQ of 140-149), 5 people (with an IQ of 150 or more, and 1 person with a high and low IQ (below 120) in the population is about 87%.

An IQ of 120 is in the upper middle range. The average IQ of a normal person is 90 110 points. IQ is usually calculated on a 200-point scale, with a score below 70 usually mentally deficient, a score of 130 is an exceptional IQ, a score of 70 80 is a low IQ, a score of 80 90 is a lower IQ, a score of 90 110 is a normal IQ, a score of 110 120 is an upper IQ, and a score of 120 130 is an upper IQ.
Ways to increase IQ
