0×23

0×23 denotes the product of zero and twenty-three in arithmetic. The result is zero. It exemplifies the zero property of multiplication, which holds that for any number a, a×0 = 0 and 0×a = 0.

The zero property follows from the basic definitions of addition and multiplication. Since zero is the additive identity, multiplying any number by zero can be viewed as repeatedly adding zero, which yields zero. This rule is fundamental and holds across common number systems used in mathematics, including integers, rationals, reals, and complex numbers, as well as in many algebraic structures such as rings.

It is important to distinguish this arithmetic expression from similar-looking notation in programming. Some contexts use 0x23 to denote a hexadecimal literal, not a product. In hexadecimal, 0x23 equals 35 in decimal, whereas 0×23 in ordinary arithmetic equals 0. Such confusion can occur because the characters resemble each other, but they represent different concepts in different domains.

In summary, 0×23 = 0 in standard arithmetic, illustrating the general principle that multiplication by zero yields zero. This property underpins many algebraic simplifications and is a basic tool in mathematics and computer science.
