Which symbol is used to denote addition in equations?

The symbol that denotes addition in equations is the plus sign (+). This symbol is universally recognized in mathematics to indicate the operation of combining two or more numbers or values together to get a total sum. For example, in the equation 3 + 5, the plus sign signifies that the values 3 and 5 are to be added together, resulting in 8. Understanding the use of this symbol is fundamental in arithmetic and lays the groundwork for more advanced mathematical operations.

In contrast, the other symbols listed represent different operations: the minus sign (-) indicates subtraction, the asterisk (*) is commonly used to denote multiplication, and the forward slash (/) indicates division. Each of these symbols plays a distinct role in mathematical operations, but only the plus sign accurately represents addition.
