The four fundamental operations in math are addition, subtraction, multiplication and division. There are corresponding symbols for each operation: the plus sign (+) for addition; the minus sign (-) for subtraction; the symbols “x”, “*” and “•” for multiplication; and the obelus (÷) and forward slash (/) for division.
Addition is the process of combining two or more numbers to get their sum or total. Subtraction is finding the difference between two quantities. Multiplication is repeated addition. One of the numbers in a multiplication sentence indicates how many times the other number needs to be added to itself. Division is the inverse of multiplication.
