Final answer:
To find the sum of vectors A and B, add their corresponding components.
Step-by-step explanation:
To find the sum of vectors A and B, we add their corresponding components. The x-component of A + B is the sum of the x-components of A and B, and the y-component of A + B is the sum of the y-components of A and B.
Given that A = (3, -2) and B = (1, -1), we can add their corresponding components:
x-component: 3 + 1 = 4
y-component: -2 + (-1) = -3
Therefore, the sum of vectors A and B is A + B = (4, -3).
