Element by element. That is: Sum all the first elements to get the first element of the result; Sum all the second elements to get the second element of the result...
The vector sum is obtained by adding the two quantities. The vector difference is obtained by subtracting one from the other. Hint: 'sum' always means addition is involved, 'difference' always means subtraction is involved.

That is the algebraic answer. There is also a geometric answer.
To sum vectors a and b, draw vector a. From the tip of vector a, draw vector b. Then a + b is the vector from the base of a to the tip of b. To calculate a - b, instead of drawing b,draw the vector -b, which is a vector of the same magnitude as b but going in the opposite direction.
resultant
If a vector is given in component form <x1,y1> and <x2,y2>, then you add or subtract the corresponding components. <x1,y1>+<x2,y2>=<x1+x2,y1+y2>
Yes.
To find the sum of integers, you use addition.To find the difference, you use subtraction.
If the sum of the squares of the vector's components is ' 1 ',then the vector's magnitude is ' 1 '.
Resultant
resultant
If a vector is given in component form <x1,y1> and <x2,y2>, then you add or subtract the corresponding components. <x1,y1>+<x2,y2>=<x1+x2,y1+y2>
Vector magnitude is represented by the square root of the sum of the squares of the independent vector comonents; |V| = (x2 + y2 + z2)1/2.
Vector quantities can be added or subtracted geometrically using the head-to-tail method. To add vectors, place the tail of the second vector at the head of the first vector. The sum is the vector that connects the tail of the first vector to the head of the second vector. To subtract vectors, reverse the direction of the vector being subtracted and then add it to the other vector as usual.
The vector sum of a group of forces is zero. The vector sum of a group of forces isn't zero.
Yes.
Yes, the resultant is a vector quantity because it has both magnitude and direction. It is the vector sum of two or more vectors acting on a system.
A resultant on a vector diagram is drawn by connecting the tail of the first vector to the head of the second vector. Then, the resultant vector is drawn from the tail of the first vector to the head of the second vector. The resultant vector represents the sum or difference of the two original vectors.
The sum is the answer for adding and the difference is the answer for subtracting...
No, the statement is incorrect. The sum of two vectors of equal magnitude will not equal the magnitude of either vector. The sum of two vectors of equal magnitude will result in a new vector that is larger than the original vectors due to vector addition. The magnitude of the difference between the two vectors will be smaller than the magnitude of either vector.
Well, honey, a vector sum takes into account both the magnitude and direction of the quantities being added, while an algebraic sum just adds up the numbers without caring about which way they're pointing. It's like comparing a GPS giving you directions to a toddler stacking blocks - one's got a sense of purpose, the other's just a hot mess. So, if you want to get somewhere specific, stick with vectors; but if you're just looking to crunch numbers, algebraic sums will do the trick.
