take you sales for the last year and put it into a calculator, then press plus + and then 6 and then the per cent key %

Or

Take your sales from last year, multiply by 6 and then divide by 100. That is the amount you will increase. Add it to last years sales.

Sorry there is no "reset" for your printing calculator.

Only thing is I did not find windows 8 drivers for this printer as standard so you may run into trouble with computers running windows 8 as each computer has to have the exact operating system printer driver designed for its exact operating system .

Unless you can find windows 8 drivers somewhere on the internet

Use the words: decimal part, not decimal fractin

**Any number whose decimal part is periodic (has a recurring pattern that repeats indefinitely) is equivalent to a rational number, IS a rational number**

0.345 345 345 ... =345/999=115/333

In the following screen captures, discard the last digit if it does not belong to a period. It is the effect of rounding up of the calculator

**Period is 345**

**Period is 1**

Period is**09**

Period is** 79**

In general, if you have a decimal part of the form 0.d_1 d_2 d_3....d_n d_1 d_2 d_3 ...d_n ... where d_1 is the first digit of the period, d_2 is the 2nd digit of the period, ..., d_n is the n-th digit (and the last one) of the period, then the fraction representation of

0.**d_1d_2...d_n** d_1d_2... d_n ...=(**d_1d_2...d_n**)/(99...9) where the number of 9's in the denominator is equal to the number of digits in the period.

Once the fraction is found, one should reduce it to its simplest form.

0.345 345 345 ... =345/999=115/333

With algebra you are learning problem solving-that is the process of problem solving using rules and equations. The best way to learn it is to shut out all distraction and work at it. If there is something you don't understand you may have to go back to the beginning and learn all the principals and rules that you don't understand- Algebra can be a very hard subject but it can be concord with persistence.

How do you do standard deviation on a Casio fx115ES???? Help!

re: single variable statistics - if I simply enter three data points (5,10,15) in 'data' and then enter 'var' to see 'n', x-bar, etc., I get nothing back - it doesn't seem to have 'read' my data or done any calculation. Is there some other procedure you have to go through so the calculator knows your through entering data then 'crunch' the numbers?
