Minus minus minuend equals difference, that is, minuend minus difference equals minuend, and minuend plus difference equals minuend.
Subtraction refers to the number subtracted from the subtraction formula.
Difference refers to the number obtained by subtracting the minuend from the minuend in the subtraction formula.
The relationship between these components can be expressed as follows: the subtree subtracted from the minuend is equal to the difference, the subtree subtracted from the minuend is equal to the subtree, and the difference plus the subtree is equal to the minuend. For example, 10-5 =5, where 10 is the minuend, 5 is the subtraction and 5 is the difference.
Subtraction formula has many applications in mathematics, such as:
Calculate the difference between two numbers.
Verify the correctness of addition.
In algebra, it stands for shifting terms and solving equations.
When solving practical problems, calculate money, length and time interval.
The main function of addition formula in mathematics;
1, problem solving: We often need to use addition to solve various problems. For example, in daily life, we often need to calculate the sum of two or more quantities. In mathematics, addition can be used to solve many different types of problems, such as calculating area, perimeter and volume.
2. Establish mathematical concepts: addition is a basic concept in mathematics and the basis for learning more advanced mathematical concepts. For example, addition lays the foundation for learning algebra, calculus and other mathematical branches.
3. Solving mathematical problems: We often need to use addition when solving mathematical problems. For example, when solving equations or proving geometric theorems, addition is often the key step in solving problems.
4. Establish mathematical models: In science and engineering, we often need to use mathematical models to describe various phenomena in the real world. In these models, addition can be used to describe real-world phenomena, such as merging multiple forces and summation.
5. Algorithm design: In computer science, addition is widely used in the design and implementation of various algorithms. For example, when calculating sorting and search algorithms, we need to use addition.
