In mathematics, tick means that in multiple-choice questions or questions, tick marks are used to indicate the correctness of options or answers. A symbol with scale is a pattern consisting of a diagonal line and a vertical line, which is usually called scale. Using tick marks can improve the readability and understandability of multiple-choice questions and questions, and let students know the correct answers more clearly.

Besides using tick in multiple-choice questions, there are some other concepts and methods in mathematics that are also related to tick. For example, in the proof, some important steps and conclusions can be indicated by tick marks to reflect the rigor and logic of the proof. In addition, in the calculation process, you can also mark some completed steps or calculated quantities with tick marks to avoid repeated calculation or omission of calculation.

Generally speaking, ticking is a common symbol and method in mathematics. It can not only improve the readability and understandability of mathematical problems, but also reflect the rigor of proof and the accuracy of calculation. Therefore, in the process of learning mathematics, students need to master the usage of tick and be able to use it reasonably to solve various mathematical problems.
