## The Best The art of problem solving algebra

The art of problem solving algebra can help students to understand the material and improve their grades. Correctly distinguish the significance of the perimeter and area of a rectangle and a square, and correctly use the above four calculation formulas to find the perimeter and area. Classification: what kind of problem is perimeter? (sewing lace, fencing, fence pole, length of the path around the pond or flower bed, length of running around the playground, etc.) what kind of problem is to seek the area? Or is it related to area? (cover size of textbooks, wall painting, area of the path around the flower bed, glass for the dining table, tablecloth for the desk, floor sprinkled by the sprinkler, floor area of an item, glass, mirror, cloth, carpet, floor covering, handkerchief cutting, etc.) Student 2: I didn't understand why the sum of length and width should be multiplied by 2 to find the perimeter of a rectangle. Now I know that this is a simple algorithm to find the sum of the four sides. Learning notes series: floating point integer assignment operator example: Notes for compound assignment operator + +, -- operator meaning: calculate the area and perimeter, calculate the average score of the exam, and calculate the number of seconds in a week Common examination questions: ① know the bottom area and height of the cone, and find the volume and bottom perimeter; ② know the bottom perimeter and height of the cone, and find the volume and bottom area of the cone; ③ know the bottom perimeter and volume of the cone, and find the height and bottom area of the cone. The solution to the above common questions is usually to find the bottom radius and height of the cone, and then calculate according to the relevant calculation formula of the cylinder Type V, the transformation of perimeter problem is based on the property of angular bisector.

During this process, we use the concept of series of numbers, and use the properties of equal difference series, equal ratio series and sum of series of numbers to reasonably solve some relatively difficult mathematical problems. Although there are many ways to solve the equation, many of them are not essential. However, in addition to the most important method of solving the equation by using a rational function with a special value of the root, there are still some intrinsic essence and connections between other methods that challenge us. For example, the first solution of the cubic equation uses a variable substitution, which is obviously a special rational function. What is its fundamental theoretical basis? We don't want it to be described as a coincidence.

In the play, it seems that Lin Chaoxi traversed the parallel world with Ji Jiang because of the inspiration of a photo. In order to return to the strawberry world, he completed the task of winning the cup in the photo. His love of mathematics has become a task-based journey. Lin Zhaoxi went through three times to regain mathematics, save Lao Lin and harvest friendship. In the TV series, Lin Chaoxi and star Ji Jiang crossed the parallel world together to complete the task of winning the cup in order to return to the strawberry world.

Today, we will use matlab to explore the solution of linear equations. ⑴ in high school, we learned binary and ternary equations, which can be made by Gauss elimination method. However, with the increase of variables, Gauss elimination method is gradually difficult to solve. In order to solve the n-ary equations, people began to use determinants to solve the equations, which is Clem's law The solution of linear equations is the core of implicit finite element method. Considering the complexity of solving large-scale sparse symmetric matrix linear equations and the large number of solving libraries, as a series of articles, we will introduce it in more articles later.

## We will help you with math problems

*This app is amazing for kids it helps them understand math. It walks them step by step on the problem on how to get the answers. So, they are just not getting the answers. As a parent I don't know too much about algebra but this app works on my Android. And it has helped me with my kid’s homework. Easy to use. It's clear.*

*awesome. especially for integrals. sometimes fail to evaluate the result though, catches on mostly if I try to alter the form by some way that gets a step closer to evaluation. also, operations with the evaluated result are not working mostly. otherwise, totally recommend!!! Also, huge props to devas for keeping it free!*
