State whether true or false.
`12-15=-3`

Answer

To determine whether the statement \( 12 - 15 = -3 \) is true or false, we will evaluate the left-hand side (LHS) of the equation and compare it to the right-hand side (RHS).

### Step 1: Calculate the left-hand side (LHS)
We start with the expression:
\[ 12 - 15 \]
To perform this subtraction, we note that 15 is greater than 12. Therefore, we will subtract 12 from 15 and keep a negative sign in the result.

### Step 2: Perform the subtraction
Now, we calculate:
\[ 15 - 12 = 3 \]
Since 15 is greater than 12, the result will be negative:
\[ 12 - 15 = -3 \]

### Step 3: Compare LHS with RHS
Now we compare the LHS with the RHS:
- LHS: \( 12 - 15 = -3 \)
- RHS: \( -3 \)

Since both sides are equal, we conclude that:
\[ 12 - 15 = -3 \text{ is true.} \]

### Final Answer
The statement \( 12 - 15 = -3 \) is **true**.
