Numbers ending in 0 are ambiguous and the answer is 1 or 2.
1 The numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9 are always significant. The number 0 is only significant if it is between two of those numbers, or if it is at the end of a number that contains a decimal.
It depends on the number of significant figures from two numbers you are multiplying. But when multiplying you use the same number of significant figures from the numbers you are multiplying with the LEAST number of significant figures. Example: 92,873.239 * 2 = 200,000 (because the number 2 has only 1 significant figure even tho 92,873.239 has 8 significant figures your answer still only has 1 significant figure)
The commutative property is that the order of the operands (numbers) does not matter. So:It is true for: Adding numbers: 1 + 2 = 2 + 1 = 3Multiplying numbers: 2 x 3 = 3 x 2 = 6It is false for: Subtracting numbers: 1 - 2 = -1 ≠ 2 - 1 = 1Dividing numbers: 3 ÷ 6 = 1/2 ≠ 6 ÷ 3 = 2

The rules for identifying significant figures when writing or interpreting numbers are as follows: All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4 and 5). Zeros appearing anywhere between two non-zero digits are significant. Example: 101.1203 has seven significant figures: 1, 0, 1, 1, 2, 0 and 3. Leading zeros are not significant. For example, 0.00052 has two significant figures: 5 and 2. Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0 and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros.
-3 -2 -1 0 1 2 3
4 All of them are significant. Only zeros are potentially insignificant. And that's only when your numbers either start with zeros like 0.001 (1 significant digit 1) or end with zeros 13.0000 (2 significant digit, 13). Any zeros between non-zero numbers are significant.
