rewrite the addition sum given below using digits. Each letter is used for a different digit. Answer the questions given below
i) Which digit did you find first?
ii) How did you find R and U?
........F.O.U.R
...........O.N.E
....T.H.R.E.E
....T.H.R.E.E
_________
E.L.E.V.E.N
nOTE: fullstops are put so that the numbers don't get jumbled up

This is basically just a guessing game. We know there's a carry from T+T, so E = 1. With a little luck, I came up with
__8769
___721
_45911
_45911

101312
__9824
___871
_60411
_60411
