The second grade of elementary school had math problems of the number pattern type
There were several types of math problems in the second grade of primary school: ** 1. Arithmetic Sequence ** 1. ** Increasing Arithmetic Sequence ** - For a series of numbers like 1, 3, 5, 7,(),(), the latter number was greater than the previous number by a fixed value. In this sequence, the difference between two adjacent numbers was 2, which meant that 3 - 1=2, 5 - 3 = 2, 7 - 5=2, so the following numbers were 7+2 = 9, 9+2 = 11. 2. ** Descending arithmetic progression ** - For example, 65, 60, 55, 50,(),(). The difference between two adjacent numbers is-5, because 60 - 65=-5, 55 - 60 =-5, 50 - 55=-5, so the following numbers are 50 - 5 = 45, 45 - 5 = 40. ** 2. Multiplication Law Type (Simple Multiplication Relationship)** - For example, 24, 32, 40,? 56、？、？In this series, the numbers gradually increased and the difference was relatively stable. Considering that they had learned multiplication in the second grade, they could find that the difference between two adjacent numbers was 8, 24+8 = 32, 32+8 = 40, so the following numbers were 40+8 = 48, 48+8 = 56, 56+8 = 64. ** 3. Obtain the regular pattern between numbers through the four operations ** 1. ** Combination rule of addition and multiplication ** - For example, questions like 3×4+5 = 17 needed to observe the pattern of the results obtained by different combinations of numbers. 2. ** Rule of addition ** - For the sequence 2, 6, 10, 14,(), 22, and 26, the difference between two adjacent numbers is 4, 2+4 = 6, 6+4 = 10, and 10+4 = 14. Therefore, the number in the parenthesis is 14+4 = 18. 3. ** Subtraction Rule ** - For example, in the sequence 33, 28, 23,(), 13,(), and 3, the difference between two adjacent numbers was 5, 33 - 5 = 28, and 28 - 5 = 23. Therefore, the number in the first bracket was 23 - 5 = 18, and the number in the second bracket was 13 - 5 = 8. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What does it mean in elementary school math?
Elementary math covered many concepts, and the corresponding math questions revolved around these concepts: 1. ** Understanding and calculation of numbers ** - ** addition **: For example, the problem of combining two or more numbers. For example,"Xiao Ming has four apples, and Xiao Hong gave him six more. How many apples does Xiao Ming have now?" This needed to be solved with the addition formula 4 + 6 = 10, which meant that the number of four apples and six apples were combined. - ** Subtraction **: It involves removing a part of a number to find the remainder. For example,"There are 10 birds on the tree, 6 have flown away, how many are left", the formula 10 - 6 = 4 represents the number of birds left after deducting the 6 birds that flew away from the total of 10 birds. - ** Multiplication **: A simple operation that represents the sum of several identical addenda. For example,"There are two pieces of chocolate in each box. Mom bought five boxes. How many pieces of chocolate are there in total?" could be written as 2×5 = 10. The 5 here meant that there were five 2s added together. - [Division]: It is an average or an operation that involves finding a number that contains several other numbers. For example,"Mom made 10 buns and divided them evenly among 5 people. How many buns did each person get?", 10/5 = 2 meant that the 10 buns were divided equally into 5 portions, and the number of buns per portion. 2. ** Score related ** - It mainly involved the representation of the relationship between parts and the whole. For example,"Mom bought 100 apples and gave 4/10 to the older brother. The younger sister gave the rest. How many apples does the younger sister have?" The 100 apples were divided into 10 portions, and the older brother gave 4 of them. The number of apples that the younger sister got was calculated through the scores. 3. ** In terms of ratio and percentage ** - ** ratio **: It represents the relationship between two numbers. For example,"Mom bought 100 apples, and the ratio of the number of apples given to the brother and sister is 4:6. How many apples did they each get?" Through the ratio, the number of apples that the brother and sister each got was calculated. - ** %**: A number that represents how many percent of a number is another number. For example,"Mom bought 100 apples and gave 40% to her brother. The younger sister gave the rest. How many apples does the younger sister have?" The 100 apples were regarded as 100%, and the number of apples for the younger sister was calculated according to the percentage distribution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Elementary School Mathematics Ancient Interesting Problems
The following are some of the interesting ancient math problems in primary school: ** I. The problem of "things do not know their numbers" in Sun Tzu's Arithmetic Classic ** 1. ** Title ** - There was a pile of items, 3 3 left 2, 5 5 left 3, 7 left 2. Find the number of items in this pile. 2. ** Solution Method ** - The total number of items was not unique. It was an arithmetic progression with a difference of 3×5×7 = 105. Each answer could be broken down into the sum of three numbers. The first number could be divided by 5 and 7, and the remainder after dividing by 3 was 2; the second number could be divided by 3 and 7, and the remainder after dividing by 5 was 3; the third number could be divided by 3 and 5, and the remainder after dividing by 7 was 2. - It was easy to deduce that the first number was 140, the second number was 63, and the third number was 30. Then, 140+63 + 30 = 233 was a solution to the original question, and 23, 138, 233, and 338 were all solutions to the original question. ** II. The problem of "pheasants and rabbits in the same cage" in Sun Tzu's Mathematical Classics ** 1. ** Title ** - Today, there are chickens and rabbits locked in a cage. There are 35 heads and 94 feet. How many chickens and rabbits? 2. ** Solution (One of the Arithmetic Methods)** - Think about it with rabbit feet as the main element: Imagine that the first 35 are all rabbits, then there should be 35×4 = 140 feet, so there are 46 more feet. You can replace the same number of chickens with rabbits to reduce the number of feet. Every time you remove a rabbit (exchange a chicken), you will lose 2 feet. - Therefore, the number of chickens was 46 div2 = 23, and the number of rabbits was 35 - 23 = 12. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
