Why is it important to be able to determine the number of significant figures properly?

For any arithmetic operation, the number of significant digits in the operands determines the maximum number of significant digits in te answer. There is no point in trying to calculate a highly precise answer if your operands cannot justify it.
For example, if you are using pi = 3.14, (3 sf) then there is no point in measuring the radius of a circle to 7 sf and giving its area to 10 sf.

Why are significant figures not important in math class?
They ARE important.
Determine the number of significant figures for 28.6 grams?
Three - all nonzero numbers are significant.
How many significant figures does this number have?
In order to determine the number of significant figures in a number, you need to look at the non-zero digits and any zeros between them.
How do you use significant digits to determine how to report a sum or product of two measurements?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
How many significant figures does 20.2 have?
20.2 has three significant figures.
Why is significant figures important is measurement?
Significant figures are important in measurement because they determine how accurate a scientific claim can be. There always has to be a small amount of uncertainty in an answer, because no measurement or calculation is ever 100% absolute.
What is the number of significant figures in 546 km?
3 of them.
How do you determine how many significant figures to keep in an answer obtained by adding and subtracting?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
What is the rule you use to determine the number of significant figures in the results of addition and subtraction?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Determine the number of significant figures of 2603000?
4 of them.
Why are significant figures not important in math class?
They ARE important.
How many significant figures should be reported in the answer -2.006?
Three, so the answer would be 3.96. Always use the number with the smallest amount of significant figures to determine the amount of significant figures will be in the solution.
Determine the number of significant figures in each measurement 12.90s?
4 of them.
Determine the number of significant figures in 1.056 ml?
1.056ml has four significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
Determine the number of significant figures for 28.6 grams?
Three - all nonzero numbers are significant.
How many significant figures are there in measurement 40 500?
There are three. The 4, the 5 and the zero in between. The two last zeros serve only to properly space the decimal point which, in this number, is implied.
How many significant figures does this number have?
In order to determine the number of significant figures in a number, you need to look at the non-zero digits and any zeros between them.
