The missing number is 2.
Solución
To solve for the missing number in the equation:
\[
(-7) \cdot \,?\, = -14
\]
Follow these steps:
1. **Set Up the Equation:**
\[
-7 \times x = -14
\]
2. **Isolate the Variable \( x \):**
To find \( x \), divide both sides of the equation by \(-7\):
\[
x = \frac{-14}{-7}
\]
3. **Perform the Division:**
\[
x = 2
\]
4. **Conclusion:**
The missing number is **2**.
**Verification:**
\[
-7 \times 2 = -14
\]
The equation holds true, confirming that the missing number is indeed **2**.

To solve for the missing number, think of what you need to multiply \(-7\) by to get \(-14\). If you take \(-14\) and divide it by \(-7\), you find that the answer is \(2\). So, \( (-7) \cdot 2 = -14 \)! Now, let's explore how negative numbers work in multiplication! When you multiply two negative numbers (like \(-7\) and \(-2\)), they turn positive, which can often be a surprising twist in math. This is due to the rule that says "a negative times a negative equals a positive." So, don’t be afraid of those negatives—embrace them!
