Which mathematical symbol is used for addition?

The mathematical symbol used for addition is the plus sign, represented as "+". This symbol is universally recognized in mathematics and indicates that two or more quantities are to be combined or summed together. For example, in the equation 3 + 2, the plus sign shows that we are adding 3 and 2, resulting in a total of 5.

The other symbols serve different functions— the minus sign "-" is used for subtraction, the asterisk "*" often represents multiplication, and the forward slash "/" indicates division. The use of the plus sign is fundamental in arithmetic operations and is key to understanding more complex mathematical concepts.
