Hi, I am getting very frustrated. I am doing an online homework for chemistry and it's telling me to round to the nearest WHOLE number.
So the answer I got was 1435.650....
And I typed in 1436. and said I was wrong and so I tried it again and typed 1.4 x 10^3, wrong again. The answer they gave was 1.44 x 10^3
Another problem: answer was 3623.895556
So I tried the answer 3.62 x 10^3, wrong.
The answer was 3.624 x 10^3
How do you round to whole numbers? I keep on getting these problems wrong just because I don't round correctly. Help please!

I agree that 1435.65 rounded to nearest whole number = 1436 or 1.436 * 10^3.
Although it is rare, sometimes book answers are in error. Check with your teacher.
However, I would agree with 3.624 * 10^3 for the second problem.
