Udemy has not yet generated a profit as is common among high-growth startups who invest heavily in their own growth. [25] Udemy reported net losses of $69.7 million for 2019 and $77.6 million in net losses for 2020. By June 30, 2021, Udemy had an accumulated deficit of $407.9 million. In 2020, Udemy spent $192.6 million on marketing and ...
German mathematician Carl Friedrich Gauss said, "Mathematics is the queen of the sciences—and number theory is the queen of mathematics." Number theory also studies the natural, or whole, numbers. One of the central concepts in number theory is that of the prime number , and there are many questions about primes that appear simple but whose ...
The apparent plural form in English goes back to the Latin neuter plural mathematica , based on the Greek plural ta mathēmatiká (τὰ μαθηματικά) and means roughly "all things mathematical", although it is plausible that English borrowed only the adjective mathematic(al) and formed the noun mathematics anew, after the pattern of ...
Poster, entitled "MOOC, every letter is negotiable", exploring the meaning of the words "massive open online course" A massive open online course (MOOC / m uː k /) or an open online course is an online course aimed at unlimited participation and open access via the Web. [1]
Differential 0-forms, 1-forms, and 2-forms are special cases of differential forms. For each k , there is a space of differential k -forms, which can be expressed in terms of the coordinates as ∑ i 1 , i 2 … i k = 1 n f i 1 i 2 … i k d x i 1 ∧ d x i 2 ∧ ⋯ ∧ d x i k {\displaystyle \sum _{i_{1},i_{2}\ldots i_{k}=1}^{n}f_{i_{1}i_{2 ...
reading and mathematics, for which children are tested in grades 3 through 8. “If a child fails the test, she is judged not to have received a good education from the school. If the school does not make Adequate Yearly Progress (AYP) on student test scores, the school is considered not providing a good
Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous.In contrast to real numbers that have the property of varying "smoothly", the objects studied in discrete mathematics – such as integers, graphs, and statements in logic [1] – do not vary smoothly in this way, but have distinct, separated values. [2]
The Clay Mathematics Institute officially designated the title Millennium Problem for the seven unsolved mathematical problems, the Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier–Stokes existence and smoothness, P versus NP problem, Riemann hypothesis, Yang–Mills existence and mass gap, and the Poincaré conjecture at the ...
