The Mystery of Mathematics: Elementary School Introduction
Based on context alone The mathematics mysteries of elementary school were rich and varied. ** 1. The Mystery of Numbers and Operations ** 1. ** The law of numbers ** - There were many rules in natural numbers, such as the alternating occurrence of odd and even numbers. Odd numbers are like 1, 3, 5, etc., which cannot be divided by 2; even numbers are like 2, 4, 6, etc., which can be divided by 2. There was a difference of 2 between adjacent odd or even numbers. - The combination of numbers was also very interesting. For example, if a two-digit number, a ten-digit number and a single-digit number exchanged positions to obtain a new number, and there was a certain relationship between the two numbers. For example, the difference between 23 and 32 was 9 (32 - 23 = 9), and this difference was the same as the difference between the two numbers (3 - 2 = 1) multiplied by 9. 2. ** The magic of calculation ** - The addition and the substitution were the converse operations. For example, 3+5 = 8, then 8 - 5 = 3, 8 - 3 = 5. It was like a balance. If addition was like putting something into a box, then substitution was taking something out of the box. - Multiplication was a simple operation to sum the same addend. For example, 3+3 + 3 + 3+3 = 15, which was 3×5 = 15. Division was the inverse of multiplication. 15 div3 = 5 meant that there were five 3s in 15. - In multiplication, there were some special combinations of numbers, such as 11 multiplied by a two-digit number. 11×12 = 132. The calculation method was to add the 10-digit number 1 and the 1-digit number 2 of 12 to obtain 3. The result was obtained by placing it between 1 and 2. ** 2. The Mystery of Geometries ** 1. ** Planar Diagram ** - The triangle had stability, and many buildings in life would take advantage of this feature. For example, the frame of a bicycle would not easily be deformed even if it was subjected to external forces. The sum of the internal angles of a triangle was 180°. This rule was satisfied regardless of whether the triangle was an acute triangle, a right triangle, or an obtuse triangle. - A square and a rectangular are both quadrilateral, and the sum of their internal angles is 360°. The four sides of a square are equal and the four corners are all right angles, and the opposite sides of a rectangular are equal and the four corners are also right angles. From a rectangular shape, a quadrilateral could be derived. The opposite sides of the quadrilateral were parallel and equal, and its area was calculated by multiplying the base by the height. 2. ** Three-Dimensional Image ** - A cube was a special cuboid. Its six faces were all squares. The sum of the edges of the cube was equal to the length of the edges multiplied by 12, the surface area was equal to the square of the length of the edges multiplied by 6, and the volume was equal to the cube of the length of the edges. - The cylinder had two identical circles on the bottom and a rectangular shape on the side. Its volume was calculated by multiplying the base area by the height, and the surface area was the two base areas plus the side area. ** 3. Mathematics in Life ** 1. ** Math in shopping ** - When we go to the store to buy things, we use math. For example, if the original price of a piece of clothing was 100 yuan, the price after the 20% discount would be 100 x 0.8 = 80 yuan. If he had a coupon, he could further reduce his expenses. 2. ** Mathematics in Time Calculation ** - Calculating the time that had passed was also an application of mathematics in life. For example, from 8 am to 3 pm, a total of seven hours had passed. It could be calculated by converting 3 pm to 15 pm (12 + 3 = 15), and then 15 - 8 = 7 hours. Read more exciting novels for free
