So a hardware store sells a $5 multimeter that has a clamed acuracy of 0. 5 On dc 0. 5 On ac 1 on ohm and 1 on curent. can some one explina how this is posible

Kiriakos-GR:
Well my friend, by reading your text I stayed frozen for five minutes before I press the reply button.

There is thousands products out there, and new products are made every day.
Why should any one care to study an 5$ multimeter ?

Scuse my typing i was doing it on a phone anywaye this is the meter http://www.harborfreight.com/7-function-digital-multimeter-90899.html and the nubers are the acuracys

I have two of them.  They are fairly accurate.  What you pay for in a $50 multimeter are a couple things. 

1 - They is a much less likely chance of dying when you use on mains voltage.
2 - When you drop them, they still work. 
3 - The make measurements that are accurate through ranges.  Comparing these to "real" meters, usually prove their accuracy numbers to be lies.
4 - The probes are actually insulated to a level that makes them safe to use in higher voltages.  I've had one lead on a cheap meter crack.  Had I not noticed it, that crack could jump directly to me.

If all you are doing is 12V or less hobby projects.  You can get by with a $5 meter.  Never trust it for anything past that.

Add to that list
5 - Will be mush less likely to explode in fault conditions. See this video
