PLUS AND MINUS SIGNS Meaning and
Definition
-
Plus and minus signs are mathematical symbols used to represent two different operations: addition and subtraction.
The plus sign (+) is a symbol used to indicate addition. It is placed between two or more numbers to indicate that they should be added together. For example, in the equation 2 + 3 = 5, the plus sign signifies that 2 and 3 should be combined to give a total of 5.
On the other hand, the minus sign (-) is used to represent subtraction. It indicates that one quantity should be taken away from another. In the equation 8 - 4 = 4, the minus sign denotes that 4 is subtracted from 8, resulting in a difference of 4.
Both symbols are essential in basic arithmetic and algebraic calculations. They are commonly used in mathematical equations, formulas, and expressions to perform operations such as addition or subtraction. The plus sign and the minus sign are part of the foundation of mathematical notation, allowing for concise and accurate representation of mathematical operations.
Additionally, the plus and minus signs can also be used to indicate positive and negative values respectively. For instance, a positive number is denoted by a plus sign (+) placed in front of it, while a negative number is indicated by a minus sign (-) placed in front of it. These signs play a crucial role in representing the concepts of positive and negative quantities in mathematics.
