The number whose farthest right significant digit determines it. Whatever place that digit is in is the last significant digit in the sum. For example: 433 + 150 + 3.67 + 8000 = 8586.67, but in sig figs this is only 9000, as the thousands digit is the lowest digit that can be represented.

Zeros appearing anywhere between two non-zero digits are significant. Trailing zeros in a number containing a decimal point are significant.

It is optional. I prefer reporting " reasonable " digits.

That the last number is 5 means you round the second to last one up. This gives you .0943. However, 3 is the last number now, and that doesn't let one round up. So you are at .094. Four is the last number, and it does not allow you to round up. So you are left with the last two digits of .09, which are the two significant figures.

Significant figures are basically the amount of digits in a number. E.g. 2.576 has 4 significant figures 32.545 has 5 significant figures Zeroes before the first non-zero digit and after the last non-zero digit are not counted as significant figures. E.g. 0067.4 has 3 significant figures 67.400 has 3 significant figures 0067.400 has 3 significant figures. In case of thermometer measurement of normal temperatures maximum three digits are significant because most of the thermometers indicate one digit after decimal; as 37.4.

Throw it away. That's what rounding means.Before doing so, though, depending on the rounding method you're using you may need to look at it. In general you round the last digit kept down if the next digit is 0-4, and round the last digit kept up if the next digit is 5-9, but there are some fiddly little details that result in a variety of methods.
