The expression "6 + 8" represents a simple addition problem in mathematics. In this case, the number 6 is combined with the number 8 to find the total. Addition is one of the four basic arithmetic operations, which also include subtraction, multiplication, and division. When you add 6 and 8, you count up from 6 by 8 more units. This results in a total of 14. Therefore, the solution to the equation "6 + 8" is 14, which can also be visualized using objects, such as 6 apples and 8 apples, resulting in 14 apples altogether.
