Vector addition is basically similar, with respect to many of its properties, to the addition of real numbers.
the opposite to vector addition is vector subtraction.
No, it is not.
Yes subtraction of vector obeys commutative law because in subtraction of vector we apply head to tail rule
No, changing order of vectors in subtraction give different resultant so commutative and associative laws do not apply to vector subtraction.
NO
It's impossible as the addition of two vectors is commutative i.e. A+B = B+A.For subtraction of two vectors, you have to subtract a vector B from vector A.The subtraction of the vector B from A is equivalent to the addition of (-B) with A, i.e. A-B = A+(-B).
No. It is the same as when you subtract normal numbers. a - b is not the same as b - a. However, if you convert the subtraction to an addition, you can use the commutative law - both with normal subtraction and with vector subtraction. That is, a - b, which can be written as a + (-b), is the same as -b + a.
He commutes from the suburbs to the city everyday for his job.
John commutes to work every morning.
Similar to subtraction of real numbers, to subtract a vector means to add the opposite vector. Here is an example: Subtract (5, 3) - (2, -2) This is equivalent to (5, 3) + (-2, 2) Add by components: (5-2, 3+2) = (3, 5)
An operator is a mapping from one vector space to another.
Think commute (like somebody who commutes to work), and then think of 'move around'. Addition and multiplication are commutative: X + Y is the same as Y + X. A*B is the same as B*A (the * means to multiply) Subtraction and division are not commutative.
