# Put a number on both sides [closed]

Make the following equation correct by putting an exact same number on both sides of the equation. The final equation must be an "equal to" equation only. No "less than or greater than" allowed.

• Just to clarify, are we restricted to putting one instance of the number on each side? Commented Feb 7, 2023 at 13:21
• Same number. For example if you put say 8 somewhere on the left hand side, you must put 8 somewhere on the right hand side. Commented Feb 7, 2023 at 13:27
• Would a 'calculation-puzzle' or 'lateral-thinking' tag be appropriate here? (It's not really a traditional 'riddle' type question so I've removed that tag for now...)

• It is not a calculation but some lateral thinking could work Commented Feb 7, 2023 at 13:54
• Now that this has an accepted answer, it looks like it was a "guess what I was thinking" puzzle. The first posted answer is at least as valid as the accepted answer.

An unconventional solution:

Add V (5) to both sides like this:

>< = v
______^

i.e. X = X in Roman numerals.

• To me this feels like a more intuitive answer than the accepted one. Commented Feb 8, 2023 at 19:51

Left hand side is a bit tilted:
