The Equation
Thursday, September 11th, 2008 running time 08:08
A stumper of a puzzle‚ using only 4th grade math.
Effect: Using matches (or in our case - toothpicks), create the incorrect math equation 1+11+111=1111. Then challenge your friend to move only 1 match and make the equation true. Make sure to point out that the 4 matches on the right side of the equation are correct; it‚ only the left side that needs fixing. To be even more fair, point out that they can interpret the numbers as roman numerals, hash marks, or traditional Arabic numerals (in truth, all these extra options only serve to make the puzzle even harder).
Method: Take one of the matches from the 11 section, turn it 90 degrees and place it perpendicularly over the middle match in the 111 section. Properly spaced, the equation then appears as 1 + 1 + 1 + 1 = 1111!

Another Great Ep.
I actually paused the video thinking, "Ok I can Solve this" after about a minute I gave up and watched the video.

Hmm.. how about moving the toothpick from the 2nd + making it a - sign and making the III into VII? Like I + II - VII = IIII ( 1 + 2 - 7 = 4 ). I thought that was the answer tbh... roman numerals FTW.
edit: actually that is -4.. damn, I fail at math.
double edit: Actually... I + VI - III = IIII (1 + 6 - 3 = 4) works out. Aside from the fact that 4 is really IV, but it still works, right?

While Brian said the sum was correct, he didn’t say you couldn’t change it.
I + I I + I I I = I I I I
By move one tooth pick from the set of 3 to the other side of the equals sign you get:
I + I I + I I = I I I I I or 1 + 2 + 2 = 5
Arguably a right answer.

I + I I + I I I = I I I I

I + I I + I I = I I I I I or 1 + 2 + 2 = 5

Hey Gavin -
Actually at 2:04, Brian explains that the last half of the equation is "right". Meaning you cannot move those toothpicks (or the sum).
Also, as an outtake at the end of the episode, we show you that *not* setting up the trick properly can result in the answer you posted.

It doesn't make sense for one side of an equation to be valid. Either an equation is true or it is false. However, the rules of the game stipulate that you cannot change the right-hand-side.

"right"
Gotcha. I probably shouldn't have use the word "right". I should've just said that the "rules of the game is to not move anything at the end of the equation".

l+ll+lll=llll
Take one of the l for the lll and lay it across the llll and you have
l+ll+ll=five in tally marks

l + ll + lll = llll
Use the first toothpick in the lll to cross over the second toothpick in lll. You get
l + ll + + l = llll
or, for those that still don't see it
l + ll + 0 + l = llll
Simple, easy, and elegant.

It is ironic that we've come so far, that the last way a person would think to solve this addition problem is the first way they were taught to think about addition.
