f={(4,5),(5,6),(6,-4)}" and "g={(4,-4),(6,5),(8,5)}" then find "(ii)f-g

If f={(4,5),(5,6), (6,-4)} and g={(4,-4),(6,5),(8,5)} then find: (i) f+g, (ii) f-g, (iii) 2f+4g, (iv) f+4, (v) fg, (vi) f/g, (vii) |f|, (viii) sqrt(f) , (ix) f^(2) , (x) f^(3)

if f={(4,5),(5,6),(6,−4)}, g={(4,−4),(6,5),(8,5)} then find f+g
