Solve the Multiplication Equation: ? × 1 = 63

$?\times1=63$

We need to solve the equation $? \times 1 = 63$. The number we are looking for is such that when multiplied by 1, it gives the product 63.

According to the Identity Property of Multiplication, any number multiplied by 1 is equal to the number itself. This can be expressed as $a \times 1 = a$ for any number $a$.

Therefore, in the equation $? \times 1 = 63$, the unknown number $?$ must be $63$ because:

• Step 1: Use the Identity Property $a \times 1 = a$.
• Step 2: Substitute 63 for $a$, since 63 is the result on the right side of the equation.
• Step 3: Realize that the unknown number is $63$, since multiplying 63 by 1 does not change its value.

Consequently, the correct answer is that $? = 63$.

The solution to this equation is 63.
