Question about Texas Instruments TI-30X-IISTK Scientific Calculator

How do I get the TI-30X IIS to give standard Percentages? For example, 100+ 10% is 110. But when I entered this into the calculator it gives the answer as 100.1. So, how do I get it to give the correct answer? The calculator is in ''Grad'' mode, not sure if this is part of the problem, Thanks so much!

For the 30Xa you may download the manual (TI calls it a guidebook) from here. TI doesn't have a guidebook for the 30X IIS, but you can get the quick-ref and teacher's guide from here.

You don't. The 30X IIs runs on both solar power and a 2025 lithium battery. If you need to replace the 2025 battery, see this.

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.

The following examples will demonstrate how to
convert decimals into fractions using the TI-30Xa and TI-30Xa Solar.
Please be aware that TI-30Xa Solar School Edition calculators do not
have this functionality.

**Example**: Convert .25 to 1/4

- Input .25, press [2nd][<--] (says F<>D above it).

**** F<>D means fraction to decimal, decimal to fraction. **

**Example**: Convert 1.38 to 1_19/50

- Input 1.38, press [2nd][<--].

**Example**: Convert 9.75 to 9_3/4

- Input 9.75, press [2nd]{<--].

- Input .25, press [2nd][<--] (says F<>D above it).

- Input 1.38, press [2nd][<--].

Press 2nd [STAT] then select CLRDATA to clear statistics data. Select 1-VAR or 2-VAR for one-variable or two-variable statistics. Press DATA and enter your data (x for 1-VAR or x and y for 2-VAR). Press 2nd [EXIT-STAT] and select N. Press STAT-VAR to see a menu of statistics variables and their values. Sx (and Sy) will give you the standard deviation, sigma-x (and sigma-y) will give you the population 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.

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
