KCKC-101 - 和差 - 回答 | 和差 - 回答 ## 和差 - 回答和差 is a mathematical concept that refers to the sum and difference of two numbers. For example, if we have two numbers a and b, then the sum of them is a + b, and the difference is a - b. The concept of and差 can be applied to various problems in mathematics, such as solving equations, finding the sides of triangles, etc.A mathematical problem that involves and差 might be something like this: "Find two numbers that add up to 17 and subtract to five." To solve this problem, we can use algebraic equations. Let the two numbers be x and y.Then, we have the following system of equations:x + y = 17x - y = 5We can solve this system by elimination or substitution. Let's use the elimination method.First, add the two equations:(x + y) + (x - y) = 17 + 52x = 22x = 11Then, substitute x into one of the equations to find y:11 + y = 17y = 17 - 11y = 6So, the two numbers are 11 and 6.And difference can also be applied to find the sides of a right triangle. For example, if we have a right triangle with sides a, b, and c (where c is the hypotenuse), then the sum of the two legs is a + b, and the difference is a - b. The concept of and difference can be used to find the sides of the triangle if we are given the sum and difference of the two legs.For example, suppose the sum of the two legs is 12 and the difference is 4. Then, we can find the sides of the triangle as follows:Let x be the length of one leg, and y be the length of the other leg.Then, we have the following equations:x + y = 12x - y = 4We can solve this system by elimination or substitution. Let's use the elimination method.First, add the two equations:(x + y) + (x - y) = 12 + 42x = 16x = 8Then, substitute x into one of the equations to find y:8 + y = 12y = 12 - 8y = 4So, the sides of the triangle are 8 and 4.the concept of and difference can be applied to various problems in mathematics, such as solving equations, finding the sides of triangles, etc.## 有什么数学问题？## 和差 - 回答In mathematics, there are several types of mathematical problems that involve addition, subtraction, multiplication, and division.
