Question
If X = `[(3, 1, -1),(5, -2, -3)]` and Y = `[(2, 1, -1),(7, 2, 4)]`, find X + Y
Solution
Given that X = `[(3, 1, -1),(5, -2, -3)]` and Y = `[(2, 1, -1),(7, 2, 4)]`
X + Y = `[(3, 1, -1),(5, -2, -3)] + [(2, 1, -1),(7, 2, 4)]`
= `[(3 + 2, 1 + 1, -1 - 1),(5 + 7, -2 + 2, -3 + 4)]`
= `[(5, 2, -2),(12, 0, 1)]`
