The problem is 150 - 1 - 0.182

Since the least sig. fig. is 1 would the answer be 1 x 10^3 ?Thanks

Well, it have no decimal places so I don't know how many significant figure should the answer be

150

-1
- .182

The answer is 150. Since the zero in the one column is not significant, you cannot subtract the 1, nor the .182

Remember the problem is really this:
(150±5)-(1±.05)-(0.182±0.0005)
and the answer is...(150±5) which in significant figure notation is 150

To solve the given problem, you need to subtract the numbers in order: 150 - 1 - 0.182.

The answer will not be 1 x 10^3 because 1 x 10^3 is equal to 1000.

To determine the number of significant figures in the answer, you need to consider the given numbers and their corresponding significant figures.

The number 150 has three significant figures because it has three non-zero digits (1, 5, and 0).

The number 1 has one significant figure because it is a non-zero digit.

The number 0.182 has three significant figures because it has three non-zero digits (1, 8, and 2).

When subtracting or adding numbers, the result should be rounded to the same number of decimal places as the number with the fewest decimal places.

In this case, the number with the fewest decimal places is 1, which has no decimal places. Therefore, the final answer should also have no decimal places.

Now let's perform the subtraction:

150 - 1 - 0.182 = 148.818

Rounding the answer to the appropriate number of decimal places, it becomes 149.

Therefore, the correct answer, considering significant figures, is 149.
