Standard Percentages on TI-30X IIS

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!

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

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 9.75 to 9_3/4

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

I'm using the TI-30X IIS calculalator and cannot calculate the standard deviation. Please help! Thank you!

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.

I just bought a texas instruments TI-30X IIS Calculator. How do I reduced improper fractions with no mixed numbers. What keys do I press. For example: 3 6/8 X 7 1/3 = ? How do I find the answer?

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
