Did you enter a negative number using the "+/-" key and not an expression using the "-" key?

As a first time user, the only way to start is to read (at least skim) through the user's guide. If you have no time for that and you need assistance with a particular question take the time to formulate it in an understandable manner. It would have been my pleasure to help you, if only I understood what you wanted. Please try again.

Use the root function, which is the shifted function of the "x-superscript-y" key, located just below the "cos" key.For example, to calculate the 5th root of 32, press32 [SHIFT] [x^y] 5 =

You can set your display mode to FIX or NORMAL ( 1 or 2) if you have them. However if the result is too small ( less then 0.001) or too large the calculator will use the scientific format. Generally if there are not enough display positions to show your result, the calculator uses scientific notation.

take menu , then take option : base . then there is a switch that says DEC , press it and now type your decimal number. Then press =. now press the switch that says BIN. Here u go .

if you want 10% of 100 multiply 100 X .10
20% of 100 multiply 100 X .20
25% of 100 multiply 100 X .25

so you get a price markup of 20% for a 100$ product 100 X.20 = 20 then add the original 100 + the 20 you got from your multiplication and you have $120.00

To use these functions press the sin, cos, or tan button followed by the angle you are looking for the value for if in degree mode or the radian value your are looking for if in radian mode.

first press (shift)...then (mode)....then (3)......then( =)
ur problem will be solved

Pressing the [a b/c] Converts the displayed value between fraction and decimal form.

In the bottom row of keys, there is a key marked [EXP]. It is lodged between the [.] decimal mark key and the [=] key. You use the [EXP] key to enter exponents of powers of 10.
To enter Avogadro's Number
6 [.]022 [EXP] 23 [=]
Be careful: You do not key in the base 10, as the [EXP] key already takes care of that.

x^y is the key just above the red C key.

The "Deg" indicates degrees are the unit used for trigonometric calculations. You can use [MODE] [5] to switch to radians or [MODE] [6] for grade. [MODE] [4] switches back to degrees. This is independent of "Comp" mode.

There is nothing special about the equation. tan(52) is just another number.
Isolate the unknown to get
X=18*tan(52)
I assume that the angle value is in degrees. To set it, press MODE 0 to use the usual computational mode, then set angle unit to degrees by pressing MODE 4.
Once this is done, type in
52 TAN * 18 =

The natural antilog function is the shifted function of the natural log key (ln). The common antilog function is the shifted function of the common log key (log).
