so so they mean that adsense cut some earnings if we come to know about the amount the we are earning from channels
It's simple really, He has two channels: Channel 1 made something like 45.6 cents, rounded up to 46 cents. Channel 2 made something like 21.7 cents, rounded up to 22 cents. When added together earnings are 67.3 cents, rounded down to 67 cents. It all balances out, on average half the people get rounded down, and half get rounded up.
At the point you took the screen shot, yes you were rounded down, but who knows, by the end of the day you may end up rounded up
Yes that is true. I can officially verify this. <joking>I am in the math league.</joking> I used three different calculators: $1 one, scientific one and the one in Windows. They stole a penny from you. lol Btw, you should have covered your email and AdSense ID. lol
