An x mark (also known as a cross, x, ex, exmark or into mark[1]) is a mark (x, ×, X, ✕, ☓, ✖, ✗, ✘, etc.) used to indicate the concept of negation (for example "no, this has not been verified" or "no, I don't agree") as well as an indicator (for example in election ballot papers or in x marks the spot). Its opposite is often considered to be the check mark or tick (or the O mark used in Japan, Korea and Taiwan). In Japanese, the X mark (×) is called "batsu" (ばつ) and can be expressed by someone by crossing their arms.[2]
