7 times 3 equals 21.
Solución
The statement "7 threes equals 21" can be expressed mathematically as:
\[
7 \times 3 = 21
\]
This means that if you take the number 3 and add it to itself 7 times, you will get 21.
To break it down step by step:
1. **Understanding the multiplication**: The multiplication \(7 \times 3\) means you are adding the number 3 a total of 7 times.
2. **Performing the addition**:
- \(3 + 3 = 6\)
- \(6 + 3 = 9\)
- \(9 + 3 = 12\)
- \(12 + 3 = 15\)
- \(15 + 3 = 18\)
- \(18 + 3 = 21\)
Thus, after adding 3 a total of 7 times, we arrive at the final result of 21.
Therefore, the statement is correct: \(7 \times 3 = 21\).
