A step pyramid or stepped pyramid is an architectural structure that uses flat platforms, or steps, receding from the ground up, to achieve a completed shape similar to a geometric pyramid. Step pyramids – typically large and made of several layers of stone – are found in several cultures throughout history, in several locations throughout ...
The pyramid scheme in the picture in contrast is a geometric progression 1 + 2 + 4 + 8 = 15. Many pyramids are more sophisticated than the simple model. These recognize that recruiting a large number of others into a scheme can be difficult, so a seemingly simpler model is used.
Symbolab is an answer engine [1] that provides step-by-step solutions to mathematical problems in a range of subjects. [2] It was originally developed by Israeli start-up company EqsQuest Ltd., under whom it was released for public use in 2011. In 2020, the company was acquired by American educational technology website Course Hero. [3] [4]
The base regularity of a pyramid's base may be classified based on the type of polygon: one example is the star pyramid in which its base is the regular star polygon. [28] The truncated pyramid is a pyramid cut off by a plane; if the truncation plane is parallel to the base of a pyramid, it is called a frustum.
In mathematics, specifically algebraic geometry, a scheme is a structure that enlarges the notion of algebraic variety in several ways, such as taking account of multiplicities (the equations x = 0 and x 2 = 0 define the same algebraic variety but different schemes) and allowing "varieties" defined over any commutative ring (for example, Fermat curves are defined over the integers).

E1 was a step pyramid similar to the Djoser Pyramid. E2 was an extension around the previous building of roughly 5 m width or 10 cubits, raising the number of steps from 5 to 7. The second extension E3 turned the original step pyramid design into a true pyramid by filling in the steps with limestone encasing. While this approach is consistent ...
