  • o i got one

    the slash across the = sign

    By NAtdni 1163229767
    • much easier than that !!!

      Turn the first plus into a 4

      By kato dude 1163532348
    • ummm

      theyre all pretty easy to me...you just need to think more for the 1st one

      By Al5ez 1182789182
    • easy

      put a line through the = so it says 5+5+5 doesnt equal 550. Still atleast this one makes sense. Unlike that 1=2 bullshit. Not bad

      nice.. :D

  • 4 Solutions!

    1. make the first sign a 4
    2. make the second sign a 4
    3. make the equal sign a "not equal to" sign
    4. make the equal sign a "less than or equal to" sign

    By belenshell 1163784827
    • No!

      Its the alligator over a flat line

      By ipodkiller 1182529851
    • Umm.... ?

      is 4th solution right?
      'less than or equal to' sign is '≦', isn't it?
      this problem riquires the 'single straignt line',
      so i think 4th is not solution.

      By Clavis 1165406845
    • 4th is a Solution

      The less than or equal to sign in a left facing arrow over another line. Make one diagonal line to make the top line the arrow.

      By Mathlete08 1167274282
    • but...

      15 is less than 550....but it is not equal to....
      So you cant have the less than or equal to sign?

      By Mark_1234 1170380317
    • lol...

      ok that was just stupid. Following your logic 15 would have to be less than AND equal to 550 for that sign to be used?

      The OR says it all.. "less than OR equal to" it doesn't have to be both at the same time, which by the way is impossible obviously..

      By eljafigo 1170523473
  • I think I found a new solution

    Put a single line in front of one of the 5's making it a variable and then solve!

    5l + 5 + 5 = 550

    5l = 540

    l = 108

    Basic Algebra. And hey, it's true right!?

    By mtspknwildcat 1184143489
    • lol

      That's true man xD

      By Czarek1 1185014763
  • I got one that reallt easy

    put a line through the equal sign
    that makes '15 isn't equal to 550'

    By thegeniusbob 1165399613
  • lol

    make a 4 out of the first plus sign

    By rebelbrett410 1217507871
  • wrong solutions guys

    turning the first plus ino a 4 works perfectly. changing the equals sign to a greater than sign will require two lines and does not support his request for support of the equation

    By dachopper 1215780540
  • wrong solution

    creating a less than or equal to sign changes the request for supporting the equation and also would
    require the use of two lines, not one

    By dachopper 1215780248
  • not a solution

    The man asked for two solutions to support the equation. Putting a line through the equals sign to negate the equation does not support his request.
    Creating a variable does

    just put a line through the whole equation and is will TRUELY be a mistake that you fixed

  • retard

    the one equals two bullshit does make sence if u knew any thing about math u can't divide by 0 retard

    such a stupid riddle i cant believe that you have earned nearly 2000$ with it .......but i think you will be very happy about this situation

  • ooo

    ooooooooo

    By jorge_alanis23 1170541927
  • i got it

    you can add a line through the equal sign like duplicate submission said or you can change the first + to 4 instead of the second + .

    By humz 1170357978
  • zzzzzzzzzzzzzzz

    5+5+5≠550

    dude zach i can't beleive you made 1.6 grand makin a small short little clever math thingy. and i see you took that missing square problem as well.
    way to make some money off this website and not making flippen crazy videos!
    respect and jealousy towards you!

    i also thought of the slash in the = sign

    dmam dude i cant believe that that is so cool wooow yea right peeps later

    he didn't lie about there being 2 solutions, he was just not as bright. two minds are better than one =)

    545+5???

    • ahhah

      very true

      By stevo203 1163452310
  • 2nd solution

    add horzantial line to the equal so it became unequal which is ture for the 5+5+5=550

    By liwa boy 1163416560
  • answer

    draw line on = so that it means unequal to

    By xerox008 1163411899
  • ridiculo!!

    ESO KEE! ... osea lo que es no tener nada que hacer, consígase una vida y cárguela a mi cuenta!

    By Alex Vortex 1163391981
  • Less Than?

    Put a diagonal slash above the equal sign to read 5 5 5<=500

    By JaxColon 1163390186
  • or

    the other possibility is to add a slash to the first plus sign :d :p
    it makes 545+5=550

    By whooocares 1163379771
  • Another Possibility

    1 Straight line ???
    How abouT Across the Equation.

    By PhoenixCo2 1163377725
    • besides...

      drawing a line through an equation that is false does not turn it into a "true statement"

      whereas leaving it as is and saying "not equal to" does turn it into a true statement

    Change the First "+" sign into a 4 instead of the second

  • i hate math

    bla bla bla.. its a foreign language

    By fh12345679 1163328290
  • i know the other solution

    the same slash on the other plus symbol gives the same value and makes the definition true..........
