Question

Which expression has the same sum as the one below?

Negative 15 + 6
15 + 6
Negative 6 + (negative 15)
15 + (negative 6)
6 + (negative 15)

Answer 1

To find which expression has the same sum as the expression "Negative 15 + 6," we can first calculate the sum of this expression.

Negative 15 + 6 equals:

\[
-15 + 6 = -9
\]

Now we will evaluate each of the given expressions to see which one also sums to -9.

1. **15 + 6**:
\[
15 + 6 = 21
\]

2. **Negative 6 + (negative 15)**:
\[
-6 + (-15) = -6 - 15 = -21
\]

3. **15 + (negative 6)**:
\[
15 + (-6) = 15 - 6 = 9
\]

4. **6 + (negative 15)**:
\[
6 + (-15) = 6 - 15 = -9
\]

The only expression that equals -9 is **6 + (negative 15)**. So the answer is:

**6 + (negative 15)**.
