0×38

0×38 can refer to different concepts depending on context.

In mathematics, 0 × 38 equals 0. This is an instance of the zero property of multiplication: multiplying any number by zero yields zero. The rule is a fundamental part of arithmetic and underpins many algebraic simplifications and proofs.

In computing and digital systems, 0x38 is a hexadecimal literal. The prefix 0x (or 0X) signals that the digits that follow are in base 16. The hex value 0x38 equals the decimal number 56, since 3 × 16 + 8 = 56. The same value also corresponds to the ASCII code for the character '8'. Hexadecimal notation is common in programming languages such as C, C++, JavaScript, and Python, and is used to represent memory addresses, color values, and low-level data.

Note on typography: the symbol × is the multiplication operator, while the hex prefix uses the letter x. A form like 0×38 with a times sign is typically a typographical variant and not standard hexadecimal syntax in programming contexts.

Thus, 0×38 may appear as a simple product or, when written as 0x38, as a hexadecimal constant in computing.
