Question about Texas Instruments BA-II Plus Calculator

Hello,

Your notation expression contains an extra symbol ( either the - or the second x).

If I enter

(1.9x10^10)x453.6/163871 I get 5.262148845 x 10^7 about 5.3 x10^7

If I enter

(1.9x10^10 - 453.6)/163871 I get 1.159 x 10^5.

Your result is off by a factor of 100 to 10000.

As to the scientific display mode, you set it by pressing [MODE][->][SCI][ENTER] [2nd][QUIT]. You can leave the Float option to 9 digits if you want.

Hope it helps.

To switch out of scientific notation, press SHIFT MODE then select Fix or Norm.

Be aware that the calculator will switch to scientific notation anyway if the magnitude of the answer is too large or too small.

Your answer is 6.7*10^18. That requires 19 places on the display: There are not enough places to write that. Besides, calculators are deigned to use Scientific Notation whenever the result to be displayed is too large or too small.

If you enjoy writing zeros, convert by hand the scientific notation into what you call long number.

Clear the calculator.

Press [SHIFT][9] (CLR) or [SHIFT][MODE] (Setup) 8:Norm and choose Norm1 or Norm 2. Select the number of digits.

That IS the correct answer.

0.2^12 = 0.000000004096

In order to get this number to fit onto the screen the calculator switches to scientific notation, showing the number as 4.096 times ten to the minus 9.

Engineering notation ALWAYS puts the exponent as a multiple of three (kilo, mega, giga, etc). If you want the exponent as it is, use scientific notation. You can put the fx-115EX into scientific notation by pressing SHIFT MODE 7 and then entering the number of digits you want after the radix mark. Unfortunately there is no way to have the calculator adjust both the mantissa and exponent by anything other than three.

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.

"FIX" mode is the number of decimal places, When you say Fix-0 it will truncate the decimals.

Either set model FIX-4 or FIX-5 or better still, just regular COMP mode.

Shift-clr-2 (mode) should set it back to defaults.

If you're sure the answer isn't really 1.007, check to see if the calculator is in fixed mode. You can change it to scientific notation(that'll give you lots of digits past the decimal place, or I prefer engineering, which is scientific except all powers of ten are in multiples of three).
