That's clever. Good job.

Dumbell submitted this and holiday destinations after she left the pc for justlongenough for a login to be changed. I hope she sees the funny side as her other submitted teasers so far have all turned out to be doubles!

Actually, on a two dimesional plane, the definition of a line is "the shortest distance between two points" which of course, is a straight line.

you could make the I into a D by adding a curved line. Then in roman numerals it would be 510, which is even.

An "S" is a curve. By definition a line is straight. It is a straight curve. And it cannot be the shortest distance between two points because that would make it a distance which is a numerical measurement. The shortest distance between 2 points is traversed by a line. I know this sounds very pedantic but when you are trying to guess on of these trick teasers you need to rely on the wording being accurate or you have no chance of solving it.

Yes, a line is straight and connects two points (the endpoints). A curve is not straight, so is not a line. How did this teaser get through?

so, how about IIX (? of course, i draw my 'i's without serifs, so it works better on paper than computer screen...

yeh i wass thinking IIX.

it makes sense?

sorry, too many answers here.

Two points

IIX is not a Roman numberal. The representation of eight is VIII. For this reason IIX does not work as an answer.

If all lines have to be straight, why would the phrase 'straight line' be needed in common language? a line can be curved, looped, zig zagged, or just plain crazy.

The 'S' is comprised of 3 lines because of the serifs.

"The shortest distance between two jokes is a straight line."

"The shortest distance between two jokes is a straight line."

OK I won't get to know the answer to this question but I'll ask it anyway...

An S is a line that is curved. It has a starting point and an ending point.

What about the term "crooked line"?

Also I thought this was brilliant and hilarious!

take a line like this _____ through the center of the numeral so it becomes IV aka 4 aka ivy

Good one!

I've heard that one before. The classic 9-into-6-with-one-line problem. Very good!

Or Just ad a stright line to the bottom of the "I" to make LX = 60

Okay streuther THATS smart I never thought of that

I had seen this teaser before and thought it was funny and yes eight is VIII because 3 is III and not IIV so VII is like saying 5 + 3

I meant VIII

And by the way I'm with dumbbell on pretty much everything he said.

awesome teaser!
