It is the leading digit.
Oh, dude, the leftmost nonzero digit is basically the first digit in a number that isn't zero. Like, it's the number that kicks off the party and gets things going. So, if you see a number like 503, the leftmost nonzero digit would be 5. Hope that clears things up for ya!
0.2.
It is 5000000.
What this means is to round to the biggest digit that is not zero (the one furthest to the left that is not zero). So: 2.814 would round up to 3 because the greatest nonzero digit is the two and the digit to the right of that (the 8) is between 5 & 9. Some more examples of rounding to the greatest nonzero place: 0.00080472 ≈ 0.0008 0.330921 ≈ 0.3 (It rounds down as the number to the right of the 3 is between 0 & 4) 9.1 ≈ 9 5.942 ≈ 6
It is the leading digit.
It is front-end estimation.
The first nonzero digit in a number is the number whose product is one. THINK ABOUT IT! resources:my brain, my notes, my math book DONT RELY ON THE COMPUTER WHO KNOWS IT MAY BE WRONG.
Five. Count from the first nonzero digit to the last nonzero digit.

To round off 128,674 to leave one nonzero digit, you would round it to 100,000.
