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.
