#2 - Tricky Algebraic Equation

If,
29 - 1 = 30
9 - 1 = 10
14 - 1 = 15

Based on similar logic, Can you prove that the below algebraic equation is true?

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

#3 - Fun With Equation Puzzle

Let us say there are two natural numbers "L" and "R".
We performed eight operations on these two numbers as

Step-1: L = R
Step-2: L x L = R x L
Step-3: L^2 - R^2 = LR - R^2
Step-4: (L + R)( L - R) = R(L - R)
Step-5: L + R = R
Step-6: R + R = R
Step-7: 2R = R
Step- 8: 2 = 1

What is wrong here?

View Answer Discuss

Step5 is Wrong.
We divided the two sides by (L-R).Since L = R which indicates that (L - R) = 0 and we cannot divide by zero.
