Explanation Formula used: If vector u = 〈 a 1 , a 2 〉 and c is a real number, then, c u = 〈 c a 1 , c a 2 〉 (1) Here, a 1 is horizontal component of u , a 2 is vertical component of u . If u = 〈 a 1 , a 2 〉 and v = 〈 b 1 , b 2 〉 be two vectors, then, u − v = 〈 a 1 − b 1 , a 2 − b 2 〉 (2) u + v = 〈 a 1 + b 1 , a 2 + b 2 〉 (3) Where, a 1 is horizontal component of u , a 2 is vertical component of u , b 1 is horizontal component of v , b 2 is vertical component of v , c is any real number. Calculation: Section (1): Vector u is given as u = 〈 0 , − 1 〉 . Substitute 2 for c, 0 for a 1 and − 1 for a 2 in equation (1), to find 2 u . 2 u = 〈 2 × 0 , 2 × ( − 1 ) 〉 = 〈 0 , − 2 〉 So, vector 2 u is 〈 0 , − 2 〉 . Section (2): Vector v is given as v = 〈 − 2 , 0 〉 . Substitute − 3 for c , − 2 for a 1 , 0 for a 2 in equation (1), to find − 3 v . − 3 v = 〈 − 3 × ( − 2 ) , − 3 × 0 〉 = 〈 6 , 0 〉 So, vector − 3 v is 〈 6 , 0 〉 . Section (3): Vector u is given as 〈 0 , − 1 〉 and vector v is given as 〈 − 2 , 0 〉 . Substitute 0 for a 1 , − 1 for a 2 , − 2 for b 1 and 0 for b 2 in equation (3), to find u + v
