{{{1}}}The mvar template makes the argument italic and formats as mathematics. It is used to refer to individual variables in normal running text. It should not be used within a {{math}} template.Note that digits in a variable name are conventionally not italic so {{math}} should be used instead in for example {{math|''x''<sub>1</sub>}} to produce x1. Functions and variables made up of multiple letters are conventionally set in upright letters so {{math}} should be used in that case too; for example {{math|cos}} to produce cos.Cho ví dụ:kết quả:Hãy x là giá trị tối đa được sử dụng.
