If,
29 - 1 = 30
9 - 1 = 10
14 - 1 = 15
Based on similar logic, Can you prove that the below algebraic equation is true?
11 - 1 = 10 ?
XI - I = X
Remove I (Roman equivalent of number 1) from the LHS, you will the get the number on the RHS.
29 - 1 = 30
XXIX - I = XXX
14 - 1 = 15
XIV - I = XV
9 - 1 =10
IX - I = X
Similarly,
11 - 1 = 10
XI - I = X
