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 Little Professor is a backwards-functioning calculator designed for children ages 5 to 9. Instead of providing the answer to a mathematical expression entered by the user, it generates unsolved expressions and prompts the user for the answer.
Months after its $80 million Series B fundraise, Course Hero has acquired Symbolab, an artificial intelligence-powered calculator that helps students answer and understand complex math questions.
The Ages of Three Children puzzle (sometimes referred to as the Census-Taker Problem [1]) is a logical puzzle in number theory which on first inspection seems to have insufficient information to solve. However, with closer examination and persistence by the solver, the question reveals its hidden mathematical clues, especially when the solver ...
A node has as many children, as there are upward edges leading from the horizontal line at height . For example, in the first path for N ( 4 , 3 ) {\displaystyle \operatorname {N} (4,3)} , the nodes 0 and 1 will have two children each; in the last (sixth) path, node 0 will have three children and node 1 will have one child.
In mathematics, the Golomb sequence, named after Solomon W. Golomb (but also called Silverman's sequence), is a monotonically increasing integer sequence where a n is the number of times that n occurs in the sequence, starting with a 1 = 1, and with the property that for n > 1 each a n is the smallest positive integer which makes it possible to satisfy the condition.
The relation of one sequence being the subsequence of another is a partial order. Subsequences can contain consecutive elements which were not consecutive in the original sequence. A subsequence which consists of a consecutive run of elements from the original sequence, such as B , C , D , {\displaystyle \langle B,C,D\rangle ,} from A , B , C ...
To encode an entire formula, which is a sequence of symbols, Gödel used the following system. Given a sequence ( x 1 , x 2 , x 3 , . . . , x n ) {\displaystyle (x_{1},x_{2},x_{3},...,x_{n})} of positive integers, the Gödel encoding of the sequence is the product of the first n primes raised to their corresponding values in the sequence:
