For example, imagine a submarine is at a dangerous depth and we are interested in that fact. You might ask:
What is the temperature down there? In case they freeze down there.
What is the pressure on the hull? In case it is crushed.
What is the speed of the submarine? So they can get out of trouble quickly.
Now, the answers to the first two questions will satisfy your curiosity. They probably will freeze at -12 degrees but the hull can withstand a pressure of 12,000 megapascals, but told that the sub was going at 2 knots wouldn't help. You'd probably ask again, "Up, down, backwards or forwards?"
Pressure and temperature are NOT VECTORS in physics. They just need a quantity to show all about them. VECTORS on the other hand, like velocity, have quantity and also direction, and both of these are necessary to show them. Two knots down is very different from two knots up.
You might argue that the pressure on the top of the sub is down and the pressure on the bottom of the sub is up. This is true, but we know that information without anybody looking or telling us. It's not necessry to be told that. The direction a pressure acts is defined by the situation, but a velocity isn't given by the shape of the object or the direction it's facing.
Therefore, Vectors are qualities with quantity and direction.
For example, suppose you are in a car going at 60 mph due North and there is a cross-wind blowing at 20 mph from the west. What will be the speed and direction of the airflow over the car? If you do that, you're doing a Vector algebra sum.

What is a unit vector in mathematics?
A vector of magnitude 1.
What is an under vector room?
There does not seem to be an under vector room, but there is vector space. Vector space is a structure that is formed by a collection of vectors. This is a term in mathematics.
Which is the branch of mathematics that includes Matrices vector logic?
Linear Algebra
What is cross products?
in mathematics the cross products are the binary operation on two vectors in a 3dimensional Euclidean space that results in another vector which is perpendicular to the containing the 2 inputs vector.
What is the value of i in mathematics?
i is often used to denote the [imaginary] square root of -1. It can also be the unit vector in the horizontal direction.
What is a unit vector in mathematics?
A vector of magnitude 1.

Which is the branch of mathematics that includes Matrices vector logic?
Linear Algebra
Mathematics if a raw vector is multiplied by a column vector what is the product?
if a column vector such as x y is multiplied by a raw vector such as ( 2 0), ( 2 o) x y = 2x so 2x is the image of x y
How do you pronounce a straight line above the vowel a?
The line above a letter in mathematics means a vector whose mane is the letter. So it is pronounced "vector a"
In mathematics what term is used to refer to the quantity that has been both magnitude and direction?
Vector.
What are the importance of vector in mathematics?
They are used in a types of mathematics and can represent anything with a direction and a magnituted. Examples are temperature changes, directions you move, but many examples are far more abstract. In fact every ordered pair of numbers, (a,b) can be thought of as a vector with the origin (0,0) being one point and (a,b) being the other end of the vector. We should can the point tip and tail of the vector. However, remember, the line segment with an arrow is just a representation of the vector, it is not the vector itself.
What has the author U Koschorke written?
U. Koschorke has written: 'Differential Topology' -- subject(s): Congresses, Differential topology 'Vector fields and other vector bundle morphisms' -- subject(s): Singularities (Mathematics), Vector bundles, Vector fields
In mathematics in polar coordinates what is the polar coordinates for the point pp on a line makes an angle with the initial line?
the radius vector; and the vectorial angle the radius vector; and the vectorial angle
What is cross products?
in mathematics the cross products are the binary operation on two vectors in a 3dimensional Euclidean space that results in another vector which is perpendicular to the containing the 2 inputs vector.
In mathematics what does th area of parallelogram is equal to?
IT IS EQUAL TO THE MAGNITUDE OF THE VECTOR PRODUCT OF TWO ADJACENT SIDES
What is linear algebra?
"Linear algebra is a branch of mathematics that studies vector spaces, also called linear spaces, along with linear functions that input one vector and output another." (from Wikipedia)
