The first number is the number of minutes you begin with. The second number is the number of seconds added to your time after each move.
Time controls: Can someone explain 5/10, 5/5, 3/2, 2/1?

5+10 is when you have 5 minutes per side, after you play a move let's say take 5 secs to tihnk you'll have 4:55 minutes, then you get 10 seconds increment and it'll be 5:05

can anyone explain WHY?
Well, why not, because it is fun and challenging i suppose, and it means you keep the game alive by moving quick.

do you get the bonus 10 seconds even if you take 60 seconds to move, or do you only get the bonus if you move under a certain time? thanks for your answers.

I believe every move, no time restraints. Unless the clock is generally running low. So if you have 4sec on the clock and you make a move you now have 14sec.

Well, I guess I very hardly found one in Lebanon to be able to buy it for a pretty expensive price, 80$. I am don't have enough knowledge in marks in this subject so I can't answer that

There are apps that allow use your mobile as a clock.

Here's an example.
15/10 rapid chess is 15 minutes and a 10 second increment for each side.
10 second increment means that after each move is played, an extra ten seconds is added to your clock.
There is also Delay, which means that you have an extra few seconds before your timer starts ticking down. (per move)
Hope this helped
Sorry if only slightly off direction, but I was reading an Amazon ad for a digital chess clock that it started with the first increment and he couldn't use it in tournaments because 2:12 wasn't a valid starting time. But then I was watching chess.com or chess24 on YouTube and seen one of these grandmasters start their clock with 2:12 on it and not 2:00 then add the 12 after the first move. Which way is correct for tournament play in Canada and USA ?
Should I just buy a cheapo clock and use it for friendly games or get the kind which the Amazon reviewer got after he sent that digital chess clock back ? (A little more expensive).
30 minutes and 10 minutes are self-explanatory. What do these other time controls mean? I have searched Chess.com, but cannot find an explanation.
