It depends how many significant figures you are after. 23.1 + 2.06 = 25.16Significant figures is like rounding.If I were to round it to 3 sig. fig. I would have 25.2If I were to round it to 2 sig. fig. I would have 25and so on. You only keep the numbers which keep the number similar to the original yet less accurate with less digits.
You count the number 5 as the first significant figure,7 the second, 6 the third. You then round the it up or down from the following number. As it it 0 you round down, leaving it as 6. A: 5.76

When multiplying numbers with significant figures, round the final answer to match the number with the least significant figures in the original numbers.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
When multiplying numbers with significant figures, count the total number of significant figures in each number being multiplied. The result should have the same number of significant figures as the number with the fewest significant figures. Round the final answer to that number of significant figures.
Yes, it can be done.
The number 10.989 rounded to 3 significant figures is 11.0
When dividing numbers, the result should have the same number of significant figures as the number with the fewest significant figures in the calculation. Round the final answer to match the least number of significant figures in the original numbers.
72 is 72.2 rounded to two significant figures.

When multiplying, the number of significant numbers in the answer should be the same as the fewest significant figures in the problem. Both 13.5 and 3.00 have three significant figures, so the answer will have three significant figures. 13.5 x 3.00 = 40.5 exactly (no need to round).
Count the significant figures in each number. Calculate the minimum of these numbers. Do the multiplication Round the product to the LEAST number of significant figures, determined above.
