1×33

1×33 denotes the product of the integers 1 and 33. In decimal notation, the result is 33. The number 33 is a natural number and can be factored as 3×11. Its positive divisors are 1, 3, 11, and 33, making it a composite number.

The expression exemplifies the multiplicative identity property. The number 1 is the multiplicative identity, meaning that for any integer n, 1×n = n and n×1 = n. Therefore, 1×33 equals 33, leaving the original number unchanged. This property underpins many arithmetic rules and simplifies algebraic manipulations.

In other bases, the numeral 33 can represent different values. For a base b with b > 3, the numeral 33_b corresponds to the decimal value 3b+3, and multiplying by 1 still yields the same value, though its base-specific representation remains 33_b. Across mathematics and computer science, 1×33 is a standard example illustrating the identity element in multiplication and the stability of numbers under multiplication by 1.
