0×8

0×8 is the product of the numbers 0 and 8. In standard arithmetic, any product involving zero is zero, so 0×8 = 0.

In mathematics, 0×n = 0 for any real or complex n; this is the zero multiplication property. It is consistent with the additive identity and the distributive law: 0×(a+b) = 0×a + 0×b = 0.

Notation and interpretation: The symbol × is the multiplication operator; 0×8 should not be confused with 0x8, which in computing denotes the hexadecimal literal for the value eight. The cross symbol is common in handwritten or typeset mathematical notation. Some fonts may use a dot · to denote multiplication; the choice of symbol does not change the value.

In computing contexts, 0x8 is a hexadecimal representation meaning the decimal value 8, whereas 0×8 is read as "zero times eight" and denotes multiplication.

Examples and relevance: The zero property is foundational in algebra and is used to simplify expressions and to prove more general results via the distributive property.
