Brain Test Level 333
Question:
The equation V = IX - III is incorrect. Fix it by moving only one matchstick!
Solution:
The current equation is 5 = 9 - 3, which is 5 = 6 (False). To fix the equation by moving only one stick, you must aim to turn the V (5) into VI (6).
Drag the matchstick that represents the Roman numeral 'I' in 'IX' (9).
Place this stick next to the 'V' to change it into 'VI'. The remaining part of 'IX' becomes 'X' (10). The corrected equation is VI = X - III (6 = 10 - 3), which makes the equation visually correct based on the stick arrangement.
