Usage of the symbol ×
The symbol × is commonly used in mathematics to indicate multiplication, as in 5×3=15. It is also frequently used to mark something as incorrect or wrong, such as putting a × on wrong answers or defective items. In everyday contexts, × can serve as a quick visual cue for negation or error.
Common collocations
- 打× (dǎ ×): to mark with a ×, often used in tests or quality checks.
- ×号 (× hào): the × symbol itself.
- 乘× (chéng ×): multiplication using the × symbol.
Notes
When using × to indicate multiplication, it is typically placed between numbers or variables without spaces. When marking errors, the × is often placed directly on or next to the item to be negated. Avoid confusing × with the plus sign (+) or the letter x in handwriting, as they serve different functions.
