Press the key that is marked with a small circle, an apostrophe, and a double quotation mark. That is the DMS key. You can use it to convert from Decimal degress to DMS and back.

if you want to use your calc for this you would have to put it in as the operations to change the mixed to improper fraction i.e. input exactly as "((8*3)+6)*((3*7)+1)="  remember?  take denominator times whole number plus numerator and put over denominator to convert from mixed to improper... hope this helps

SOURCE: Standard Deviation

Press 2ND [CSR] to clear the stat data.

For each data point, enter the number followed by SIGMA+

If you have grouped data, enter the number followed by 2ND [FRQ] followed by the frequency then SIGMA+

Press 2ND [sigma x n] for the population standard deviation or 2ND [sigma x n-1] for the sample standard deviation.

You must enter 100+10%100 or 100+10%(100). This will give you the correct answer of 110.
