Add one line segment to make the following into a correct equation:

5+5+5=550

Not

No

That would make it a true statement, but an inequality is not an equation.

I can do this with 3 line segments:

.........................__

5 + 5 + 5(\) = 5 |50

(the backslash goes through the 5; I obviously don't know how to do this properly)

Hint

Alex Y

but an obtuse one :)

+24

Re: Friday extra

Last hint

Alex Y

Slope of the line segment to be added is 1

Solution

No winner on this one :(

There are two nearly identical solutions. On either of the plus signs, draw a line from the top to the left side, converting the plus to a four (sounds like "+24", my first hint). The results are the following valid equations:

545+5=550 and

5+545=550

5+5+5 is not= ( = with a slash thru it) 550 is also a valid statement.

Re: Solution

I agree,

5+5+5≠ 550

is a true statement.

But the problem asked for a correct equation, not a true statement.

1/2 credit (which is 1/2 more than anyone else got ;) )
