To find the product of \(23 \times 4\), we can use various mathematical expressions. Here are three expressions that can be used:
1. **Addition:**
\[
23 + 23 + 23 + 23 \quad (\text{adding 23 four times})
\]
2. **Multiplication (distributive property):**
\[
(20 + 3) \times 4 = (20 \times 4) + (3 \times 4)
\]
3. **Rearrangement:**
\[
4 \times 23 \quad (\text{the commutative property of multiplication})
\]
These expressions all help to calculate \(23 \times 4\) in different ways.
