SHOW AND EXPLAIN ME THE ADDATION IN VECTORS
Its very easy respective elements are added:
like consider two matrices of 3*3.
1 2 3 3 2 1
4 5 6 and 6 5 4
7 8 9 9 8 7
Then there add. will be:
4 4 4
10 10 10
16 16 16.
I hope u got it . Add first first , 2nd 2nd, 3rd 3rd and so on.

Its very easy.
Suppose the vectors are given in their resolved forms like 2i+3j+5k and 1i+2j+4k
Just add the x,y and z components like this>>>
(2+1)i+(3+2)j+(5+4)k=3i+5j+9k this is your resultant vector.
its magnitude is sq.root of 9+25+81.
Or u can add the vectors graphically.Just position them head to tail and the resutant
will be from the empty tail to empty head.
IF A = ai+bj+ck and B = xi+yj+zk where i,j,k represent unit vectors along x, y and z direction respectively
then
(A+B) = (a+x)i + (b+y)j + (c+z)k
magnitube of (A+B), IA+BI = (IAI2 + IBI2 + 2ABcos theta)1/2
i hope that u got a clear idea about addition of vectors...........
