The expression "(3+2)" represents a simple mathematical operation known as addition. In this case, the numbers 3 and 2 are combined to find their total. Addition is one of the four basic arithmetic operations, along with subtraction, multiplication, and division. When you add 3 and 2 together, you get 5. This result can be visualized using objects, such as apples. If you have 3 apples and then receive 2 more, you will have a total of 5 apples. This concept is fundamental in mathematics and is used in various everyday situations.
