Absolute magnitude is the equivalent of the mathematical operation of modulus
abs(+3) = abs(-3) = 3
However, in vector math it can refer to taking the scalar magnitude of the vector.
Eg. If V = velocity in forward direction (lets say towards the positive X axis)
then -V velocity in the backward direction (towards the negative X axis)
However, abs(V) = abs(-V) =V (which is the speed )
In geometry, magnitude is the length of the hypotenuse of a right triangle.
The magnitude of a vector is a geometrical value for hypotenuse.. The magnitude is found by taking the square root of the i and j components.
i don't know that is y i am asking what does it mean
The distance from zero.
I assume when you mean brightness, you mean apparent magnitude as opposed to absolute magnitude. The quasar 3C 273 has an apparent magnitude of about 12.8 whereas the brightest galaxy - the Large Magellanic Cloud has an apparent magnitude of 0.9. However, in absolute magnitudes, 3C 273 has an absolute magnitude of about -26.7 very similar to our own Sun.
Assuming you mean sum and not some, the answer is No.
Because the "magnitude scale is not linear, it is logarithmic (its numbers are an order of magnitude apart) this mean that the a magnitude 6 earthquake is TEN TIMES more powerful than a magnitude 5 earthquake and a HUNDRED TIMES more powerful than a magnitude 4 earthquake.

An absolute mean is a mean of the absolute magnitude of a function with both positive and negative values.
Intensity and magnitude can mean the same thing, although it is a weak connection. The word intensity generally refers to our emotions and how we feel. Magnitude refers to size.
OOM (Order of magnitude) estimate
No; the "magnitude" is how bright the star is. It can either mean:* The apparent magnitude = how bright it seems to us, * The absolute magnitude = how bright the star really is (i.e., how bright it would seem at a standard distance).
