Calculate the Average: Finding the Mean of Four 10s

To solve the problem of finding the average of the numbers $10, 10, 10, 10$, follow these steps:

• Step 1: Calculate the sum of the numbers. Here, since the numbers are identical, the sum is $10 + 10 + 10 + 10 = 40$.
• Step 2: Divide the total sum by the number of numbers, which is 4. Therefore, the average is $\frac{40}{4} = 10$.

Thus, the average of the numbers is $10$.
