My calculator keeps giving a particular error. I know that it shouldn't give this error. So eg, I do 0.95/99.05 = 9.59111.5598x10-3. It should be 0.0095. Can you please tell me how to correct this? I...
The error is in the eyes of the beholder. In scientific notation your value of 0.0095 is written as 9.5*10^(-3). Actually the calculator showed you more digits than you were asking for and its answer is more precise that yours. When you choose the Input/Output of the calculator to be LineIO, it will show the results as decimals. Howvever if the number to be displayed is too small or too large, the calculator will use the scientific notation.
To do exact calculations (whenever possible) set the Input/Output mode to MathIO. The result will be a fraction (19/1981). After that you can press the [S-D] button to convert that exact result to its decimal representation.
If you do not mind my advice, I suggest you learn how to interpret scientific notation, and familiarize yourself with the capabilities of this new type of calculators.
To configure the calculator for MathIO, press [SHIFT][MODE] to open the (SetUp), then select [1:MathIO]. In this mode, you will be able to see the expressions you type in as they would appear in a textbook:Fractions will appear as fractions, you will see radicals, etc. You can do a string of calculations in MathIO and convert only the last result to its decimal representation.
