Question 3: Determine the sum of the vectors (1, 2, 3) and (4, 5, 6)

• (6, 8, 10)

• (2, 3, 4)

• (9, 11, 13)

• (5, 7, 9)

Question 4: Find the result of subtracting the vector (8, 9, 10) from the vector (12, 15, 18)

• (-4, -6, -8)

• (4, 6, 8)

• (-3, -5, -7)

• (20, 24, 28)

Answer explanation

The correct answer is (-4, -6, -8) because we subtract each corresponding element of the second vector from the first vector.

Question 7: Find the result of multiplying the vector (4, -3, 5) by -2

• (6, -8, 10)

• (4, 3, 5)

• ( -8, 6, -10)

• (8, -6, 10)
