Convergent thinking is a term coined by Joy Paul Guilford as the opposite of divergent thinking. It generally means the ability to give the "correct" answer to questions that do not require novel ideas, for instance on standardized multiple-choice tests for intelligence .
Lateral thinking is a manner of solving problems using an indirect and creative approach via reasoning that is not immediately obvious. Synonymous to thinking outside the box , it involves ideas that may not be obtainable using only traditional step-by-step logic . [ 1 ]
The tendency to solve problems through addition, even when subtraction is a better approach. [90] [91] Attribute substitution: Occurs when a judgment has to be made (of a target attribute) that is computationally complex, and instead a more easily calculated heuristic attribute is substituted.
Divergent thinking is often contrasted with convergent thinking. Convergent thinking is the opposite of divergent thinking as it organizes and structures ideas and information, which follows a particular set of logical steps to arrive at one solution, which in some cases is a "correct" solution.
It could be said that it is the opposite of lateral thinking. [1] Unlike lateral thinking that involves using added intuition, risk taking, and imagination through unconscious and subconscious processes, vertical thinking consists of using more of a conscious approach via rational assessment in order to take in information or make decisions.
One of the widely used types of impossibility proof is proof by contradiction.In this type of proof, it is shown that if a proposition, such as a solution to a particular class of equations, is assumed to hold, then via deduction two mutually contradictory things can be shown to hold, such as a number being both even and odd or both negative and positive.
In a vector space, the additive inverse −v (often called the opposite vector of v) has the same magnitude as v and but the opposite direction. [9] In modular arithmetic, the modular additive inverse of x is the number a such that a + x ≡ 0 (mod n) and always exists. For example, the inverse of 3 modulo 11 is 8, as 3 + 8 ≡ 0 (mod 11). [10]
Fewest moves solving: The world record of fewest moves to solve a cube, given one hour to determine one's solution, is 16, which was achieved by Sebastiano Tronto of Italy on 15 June 2019 at FMC 2019, Aeden Bryant of the USA on 23 June 2024 at Ashfield Summer Challenge 2024, and Levi Gibson of the USA on 23 June 2024 at Ashfield Summer ...
