I. Add
Addition refers to addition, which is one of the four operations in mathematics. It represents the sum of two or more numbers. In addition, we use a plus sign (+) to connect two or more numbers and find their sum.
Second, subtraction.
Subtraction refers to subtraction, which is also one of the four operations in mathematics. Subtraction is subtracting one number from another. In subtraction, we connect two numbers with a minus sign (-) and subtract the second number from the first number to get the difference.
Third, multiplication.
Multiplication refers to multiplication and is also one of the four operations in mathematics. Multiplication means the product of two or more numbers. In multiplication, we use the multiplication sign (×) to connect two numbers and find their product.
Fourth, division.
Division refers to division, which is also one of the four operations in mathematics. Division refers to dividing one number by another to find the quotient and remainder. In division, we use the division symbol () to connect two numbers, and divide the first number by the second number to get the quotient and remainder.
In addition, there are some related terms, such as sum, difference, product and quotient. In practical application, these mathematical terms are very important, involving various calculations and statistical analysis.
In a word, addition, subtraction, multiplication and division are four basic mathematical operations, and their English words are addition, subtraction, multiplication and division respectively. Whether in school or in daily life, we must master these basic mathematical operation symbols and concepts.
