The expression "8 + 3" represents a simple addition problem in mathematics. In this case, the number 8 is combined with the number 3 to find the total. Addition is one of the four basic arithmetic operations, and it helps us determine how many items we have when we combine two groups. When you add 8 and 3, you count up from 8 by 3. This can be visualized as starting at 8 and moving three steps forward: 9, 10, and finally 11. Therefore, the result of "8 + 3" is 11.
