Question 68

Step 1: In multiplication, an identity is a number that does not change the other number.

Step 2: For any whole number (a), multiplying by 1 keeps it the same.

So, (a \times 1 = a\).

Also, (1 \times a = a\).

Step 3 (examples):

(5 \times 1 = 5\)

(0 \times 1 = 0\)

(23 \times 1 = 23\)

Conclusion: Because multiplying by 1 does not change any whole number, 1 is the identity for multiplication of whole numbers. Hence, the statement is true.
