Calculating Percentages.
dear tonya,
for example if u want to calculate 5% of 200 chocolates then enter 100 followed by "x"(multiplication symbol) and type 5 followed by "shift =".. u will get answer as 10..try this..
How do I enter -log(3.45x10^-11)?
I would do it the very old fashion way, but I know it will work on any calculator;)
3.45 x 10 x/y (x to the power of y) (11+/-) /* this should get you the number inside the bracket */
log /* this should give you the log of the bracket */
*1 +/- = /* this should give you the answer*/
I get 10.462180904926725879050933879218.
Good luck.
Paul
Changing decimals to fractions
You can always convert a fraction to a decimal. The reverse may not
always be possible. Look at the example on the screen capture.
You
may be lucky and recover a fraction you have just converted into
decimal format, but you cannot just write 0.333333333333 and expect the
calculator to convert it to 1/3: The true fraction 1/3 has an infinite
number of 3's after the
decimal mark.
Calculate square root nth
use the x ^1/y key. It's the shift of x^y key. So the 3rd root of 8 is found by entering 8 then shift then x^y then 3 then =
Fraction to equivalent
after typing in your fraction tap the '=' key then tap the 'a b/c' key again and it will show it in decimal
Remove decimal dot
Why? If number is decimal the dot is needed. If the result is an integer, just ignore the dot.
How to solve for future value
If you have the formula you can use the calculator to find future values. But do not count on this calculator to do it for you. It does not have a business/finance application.
