प्रश्न
Given A = `[(1, 4),(2, 3)]` and B = `[(-4, -1),(-3, -2)]` find a matrix C such that C + B = `[(0, 0),(0, 0)]`
उत्तर
A = `[(1, 4),(2, 3)]`
B = `[(-4, -1),(-3, -2)]`
C + B = `[(0, 0),(0, 0)]`
C = `[(0, 0),(0, 0)] - "B"`
= `[(0, 0),(0, 0)] - [(-4, -1),(-3, -2)]`
= `[(0 - (-4), 0 - (-1)),(0 - (-3), 0 - (-2))]`
= `[(4, 1),(3, 2)]`
