A scalar is any single number, like 27, while a matrix contains at least 2 numbers such as [27, 3].
In mathematics and physics, a scalar field associates a scalar value to every point in a space. The scalar may either be a mathematical number, or a physical quantity.
I don't see any direction mentioned there, so it has to be a scalar.
A matrix and a scalar is a matrix. S + M1 = M2. A scalar is a real number whose square is positive. A matrix is an array of numbers, some of which are scalars and others are vectors, square of the number is negative. A matrix can be a quaternion, the sum of a scalars and three vectors.
Yes, a scalar can be a negative number. For instance: c<x₁,x₂> = <cx₁,cx₂> such that <x₁,x₂> is a vector. Let c = -1 for instance. Then, we have this vector: <-x₁,-x₂> Compared to <x₁,x₂>, <-x₁,-x₂> has negative signs. In physics and mathematics, if we multiply the vector or something by a negative value scalar, then the direction of the vector is reversed, and the magnitude stays the same. If the magnitude increases/decreases, and the direction of the vector is reversed, then we can multiply the vector by any negative non-1 scalar value.
scalar lol
There is no direction in number of moles, so it is scalar.

Scalar quantities are described by a number alone, while vector quantities require a number and a direction, and as area cannot have an associated direction, must be scalar.

1000000 is a number and therefore it is a scalar. A scalar cannot be represented as a vector.
Temperature is a scalar quantity. It has magnitude but not direction.
it is scalar as readings on Any scale is scalar.
Since you can represent that with a single number, it isn't a vector - just a scalar.
A scalar means that there is no direction associated to the number. The scalar number can be associated to a mass, a length, or a speed so as long as there is no direction associated to it. If there is a direction, than it becomes a vector.
In physics, "vector" usually means that a direction is relevant. If you just have a number, as in "number of moles", then a direction is NOT relevant.
