<p>You may NOT use a calculator, or a pencil and paper for this problem.</p>
<p>Do it all in your head.</p>
<p>Take 1000 and add 40 to it. Now add another 1000.
Now add 30. Add another 1000.
Now add 20. Now add another 1000. Now add 10.
What is the total?</p>
<p>Post what you get.</p>
<p>Is it cheating if you add the 1000's first?</p>
<p>No. We will not do your homework for you</p>
<p>You're probably joking, but in case you're not...</p>

<li>This isn't homework.</li>

<p>4100??? ...</p>
<p>5000, why is this such a teaser?</p>
<p>4100...that's not hard</p>
<p>This is old, but I got 5000 the first time I did it a long time ago.</p>
<p>The answer is 4100.</p>
<p>People get 5000, because they change the number in the wrong place.</p>
<p>4100, LOL.</p>
<p>Nice trick, bet it confuses a bunch of people.</p>
<p>Not sure what's so confusing about this.</p>
<p>i got another one</p>
<p>one equals to five
two equals to ten
three equals to fifteen
four equals to twenty</p>
<p>So what does five equal to?</p>
<p>lol one? or twentyfive?</p>
<p>4100 is that supposed to confuse us?</p>
<p>five equals one according to your postulate #1. lol</p>
<p>these aren't brain teasers, lol. :P</p>
<p>i knew as soon as i said "why is this so confusing" that I was probably wrong...dammit</p>
<p>I got 5000 the first time, and 3000 on the second. how is it 4100? :D</p>
<p>and the second on is 1...</p>
<p>I got 5000 the first time around, but knowing that it couldn't possibly be so easy, I went back and added the 1000s first.</p>
<p>*** I get 4100 no matter what order I do it. Where are you "supposed to mess up"?</p>
<p>Some people add 10 to 4090 and get 5000...</p>
