A student aid assembly includes a magnetic panel that has a front side, a rear side and a peripheral edge. A plastic coating is non-removably attached to and covers the front side of the panel. The plastic coating comprises a dry erase board for displaying an erasable writing material. The plastic coating has a plurality of indicia positioned thereon and includes a blank space is bounded by a perimeter line. The blank space defines a name area to allow a person to write a name therein. The indicia includes a plurality of reference areas to assist a student with answering a school question.

A computing appliance for geometric planimetry is provided, comprising a container, a vertical dividing rule, a horizontal dividing rule, a horizontal point line and a middle point line. A fluid is filled into the container, and the vertical dividing rule, the horizontal dividing rule, the horizontal point line and the middle point line are configured on a same instructing surface of the container and arranged on each of the periphery surrounding like a rectangle. When the container is vertically disposed, a fluid level is aligned with the horizontal point line. And, when the container is tilted to form at least one angle, an area of at least one geometric shape can be derived by employing the vertical dividing rule, the horizontal dividing rule, the horizontal point line and the middle point line.

A trigonometric function display clock includes a clock face that has a center aligned with a central axis, axial markings aligned with an x-axis and a y-axis, and a secondary circle having a diameter equal to a radius of the axial markings. A first point on the secondary circle is aligned at the center of the central axis, and the secondary circle is configured to be rotatable about the first point. The secondary circle is configured to overlap and align with at least a portion of the axial markings as the secondary circle rotates about the first point.

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.

Disclosed is a modular and scalable system configured to generate a topology platform for training, entertainment, gaming, living, working, acting, viewing, etc. The platform can have a plurality of movable columns that are extendable and retractable. In some embodiments, some of the columns can be retracted to allow users to walk on the columns while other columns can be extended to form a barrier (e.g., wall) or form an inanimate object (e.g., table). The system may be used in furniture to provide topologies for highly customized support structure designs to accommodate varying body shapes, sizes, and individual comfort levels. The system may be used to generate topologies for greenscreen film stages to provide post-production editing, compositing with actors, stuntmen, and video, etc. The platform can be configurable and re-configurable to change the objects and features of the topology and represent different or dynamic environments at any time.

Apparatus and methods based on applied cognitive science, where children play the lead role in storylines staged upon a rule-enforcing apparatus and by so doing, become self-enlightened about denumerability, rank-wise denumerability, addition, subtraction, multiplication, division, and other change-of-state processes encountered in mathematics and the quantifiable sciences.
