The matrix is a 2 by 2 matrix, and the determinant of the matrix by hand is -3

<h3>How to determine the determinant?</h3>

The matrix is given as:

1     2

2     1

The determinant of the matrix is calculated using the following product expression

det |A| = 1 * 1 - 2 * 2

Evaluate the product

det |A| = 1 - 4

Evaluate the difference

det |A| = -3

Hence, the determinant of the matrix by hand is -3

The term was coined by the German psychologist and theoretical linguist Karl Bühler. It is also known as an epiphany, eureka moment or (for cross word solvers) the penny dropping moment (PDM).[1] Sudden sickening realisations identifying a problem rather than solving it, so Uh-oh rather than Aha moments are further seen in negative insight.[2] A further example of negative insight is chagrin which is annoyance at the obviousness of a solution missed up until the point of insight,[3] an example of this being the Homer Simpson's catchphrase exclamation, D'oh!.
