There are two main meanings of magnitude.
One is the absolute value. In this context, the magnitude of the number is its size, irrespective of the sign. So, the magnitude of -4 is the same as the magnitude of 4.
The other is in the sense of the order of magnitude. This is usually used when the measurement scale is logarithmic. The apparent brightness of stars, for example is expressed in magnitude. Brightest stars = magnitude 1. Stars half as bright = mag 2, quarter as bright = mag 3 etc. Or [deci]bel for the loudness of sound.
Incidentally, the Richter scale, for measuring the strength of earthquakes is not a systematic measure in this sense. The measure is largely based on the effects of the quake at the surface.
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.
The distance from zero.
Assuming you mean sum and not some, the answer is No.
An absolute mean is a mean of the absolute magnitude of a function with both positive and negative values.
Scalar quantity is when you have a magnitude but no direction such as 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.

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.
An absolute mean is a mean of the absolute magnitude of a function with both positive and negative values.
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).
