Answer
The final answer is 2.496.
Solution
1. Compute the multiplication:
\[
3.1 \times 0.160 = 0.496
\]
2. Since subtracting a negative is equivalent to addition, we have:
\[
-( -15) = +15
\]
3. Substitute the computed values into the original expression:
\[
0.496 + 15 + (-13)
\]
4. Perform the additions step by step:
\[
0.496 + 15 = 15.496
\]
\[
15.496 - 13 = 2.496
\]
Thus, the final answer is \(2.496\).

To solve the expression \( 3.1 \cdot 160 - (-15) + (-13) \), let's break it down step by step. First, multiply \( 3.1 \) by \( 160 \), which equals \( 496 \). Next, subtracting a negative is the same as adding, so \( -(-15) \) becomes \( +15 \). Lastly, add \( -13 \). Putting it all together: \[ 496 + 15 - 13 = 496 + 2 = 498. \] So, the final answer is 498. Now, wasn’t that a fun little math adventure? Remember, math can feel like a puzzle waiting to be solved, and every step is a piece coming together!
