how would you read 6.022 x 10 to the 23rd?? like if it wasn't in scientific notation? PLEASE help. millions?? trillions??

Divide the zeroes into groups of threes, as we do typographically with commas. The first group is a thousand. The second is a million. From then on they take the Latin prefixes for two (billion), three (trillion), four (quadrillion) etc. Yes it gets ugly. 10 to the 39 is a duodecillion. I suppose 10 to the 303 is a centillion.

10 to the 23rd is 100 followed by 7 groups of three zeros:

100,000,000,000,000,000,000,000

So the number in question is:

602,200,000,000,000,000,000,000

That would be read:

Six hundred two sextillion, two hundred quintillion.

By the way, as I may have warned earlier, this is the American system. In Europe they count off groups of six zeroes, not three. Their millions and billions can run into the thousands, not just into the hundreds. They would read this number as:

Six hundred two thousand two hundred trillion.

The entire phrase "six hundred two thousand two hundred" is a multiplier of "trillion." A European trillion is 10 to the 18, not 10 to the 12 as in America. We make the sacrifice of running out of pronounceable names for the exponents much earlier, in return for not having potential 12-syllable coefficients in which to get lost.

If you find that confusing, be glad you're not studying in China. They count off the zeroes in groups of four. Their civilization is so old that their language has a one-syllable word for ten thousand:

*qian*.
