Solve the Multiplication Equation: 1 × 4 = ?

To solve the problem of multiplying $1 \times 4$, we will rely on the fundamental property of multiplication by one:

• The multiplication property of 1 states that multiplying any number by 1 results in that same number.

Now, let us apply this property:

Step 1: Identify the numbers involved.
The numbers are 1 and 4.

Step 2: Apply the multiplication property of 1.
According to the property, $1 \times 4 = 4$.

Let's explain in terms of the choices:

• Option 1 ($40$) is not correct as it results from multiplying by 10, not 1.
• Option 2 ($4$) is correct because multiplying any number by 1 still gives the number itself.
• Option 3 ($10$) seems to be a misunderstanding of adding 6 to the result.
• Option 4 ($1$) is incorrect as it would suggest the result of multiplying 4 by 1 is still 1.

Therefore, the correct solution to the problem is $4$.
