A slope measurement and drawing aid (100) for teaching mathematics having unique indicia (130), rational-numeric slope values (184), and mathematical information (192), and a method of identifying the correct rational-numeric slope value associated with the graph of a given line, either by means of a gravity-activated indicator arm (140), or by means of the orientation of the teaching aid. For instructional purposes, when used in a classroom setting, the teaching aid can be removably held on a vertical board by magnetic (240R) or other means. When used in an individual setting, a smaller version of the teaching aid can similarly be used in a horizontal orientation on paper.

An information processing method includes causing an electronic apparatus to display an arithmetic setting frame in a screen of a display of the electronic apparatus. The method further includes causing the electronic apparatus to send, to outside of the electronic apparatus, mathematical expression data on a mathematical expression formed in the arithmetic setting frame by at least a part of coordinate icons being selected by a user operation. The method further includes executing an arithmetic operation based on the mathematical expression data sent from the electronic apparatus, and sending, to the electronic apparatus, arithmetic result data of the mathematical expression as a result of the arithmetic operation. The method further includes causing the electronic apparatus to display an arithmetic result of the mathematical expression based on the arithmetic result data in the screen.

A workflow deployment system comprising at least one computing device having a memory unit and a first communication unit, and a plurality of software agents, wherein each software agent is installable on an electronic apparatus of the plurality of electronic apparatuses, wherein each software agent exchanges data with the electronic apparatus, wherein the memory unit stores workflow data related to a workflow for performing a task, the workflow comprising at least a first workflow package for a first part of the task, wherein the computing device assigns the first workflow package to the first apparatus, and to provide workflow data related to the first workflow package to the software agent of the first apparatus, to receive a problem solution request from the software agent, to perform, upon reception of the request, a workflow modification process; and to provide the customized data to the software agent of the first apparatus.

Provided are a method, an apparatus, an electronic device, and a storage medium for displaying an expansion of a 3D shape, including: determining a 3D shape to be expanded, and acquiring a target expanded state of the 3D shape; searching a preset multi-level information relationship table for an articulation relationship set corresponding to the target expanded state; determining, according to the articulation relationship set and a preset expansion rule library, a target expansion rule for each target plane surface on the 3D shape; and controlling to expand each target plane surface at a predetermined a rate based on the each target expansion rule, and displaying the expansion process in real time. The method dynamically displays an expansion process of a 3D shape to a student, such that the student can understands more about the process of transformation from a 3D shape to a selected expanded state, thereby improving user experience of a teaching demonstration function on an electronic device.
