Solve 24 - Circle: Basic Subtraction with Symbol Substitution

To solve this problem, we will follow these steps:

• Step 1: Substitute the value of $\circ$ with $8$.
• Step 2: Perform the subtraction.

Now, let's work through each step:

Step 1: The problem tells us that $\circ = 8$.

Step 2: Substitute $8$ into the equation where $\circ$ appears: $24 - 8$.

Step 3: Calculate the result of the subtraction:
Start from 24 and count backward by 8 units:

• Subtracting 4 from 24 gives us 20.
• Then, subtracting another 4 from 20 results in 16.

Therefore, the solution to the problem is $16$.
