An '''exclamation point''' refers to the ! symbol. It is used for emphasis, although in formal writing, its use is generally limited. In [[mathematics]], the exclamation point means "[[factorial]]", and can be placed after integers to indicate the multiplication of that [[integer]] by all preceding positive integers . For instance, 5! can be read as "5 factorial", which means "5 times 4 times 3 times 2 times 1". 0! is defined to be 1. | An '''exclamation point''' refers to the ! symbol.
