Boot order failure

You input double parenthesis in the order that you see them in the written equation. For example, ((2+ 5)*3)+6, you would enter <left parenthesis> <left parenthesis> 2 + 5 <right parenthesis> * 3 <left parenthesis> + 6 =

Try it out on some equations to make sure it is working like you expect it to work.

Good luck.

Be careful with the order of operations. Try (ln(55)-1)/2You can never have to many parenthesis. remberr PEMDAS ln is an exponent so you want to put it inside parenthesis in oder to follow the Order of operations.

The order in which you are entering numbers and operations is not correct. For example, if you enter 5++2 most calculators will flag this as a syntax error.
On some calculators you calculate square roots as follows: 25 [SQRT]= gives 5. That is the correct syntax for this type of calculators.
For the newer ones you press the SQRT key and see displayed the square root symbol followed by a left parenthesis. You enter the number, close the right parenthesis, then =. If you do not respect the order you get a syntax error.
I cannot say more because I have no idea what you were trying to do, and more importantly, I do not know the make and model of the calculator.

According to the operation priority rules
1/1*2=1*2=2
1/2*4=(1/2)*4=2
1/2*4*6=(1/2)*4*6=12
The result is 2+2+12=16
If you have a series with increasing denominators then you should use parentheses to force the calculator to do as you intended.
1/2+1/(2*4)+1/(2*4*6)
or 1/2 +1/2/4 +1/2/4/6=31/48 or 0.645833333.....3

Are you opening the parentheses in the first place? If you don't have a left parenthesis then you don't need a right parenthesis.

Could you post the exact sequence of keystrokes you're using?

turn on your pc, press F2 or del. find the boot order, set your hard drive as your first boot priority order. press F10 and then save. hope this will help... good luck

You should be able to use parentheses in the same order in which you would write the arithmetic expression. For example, 4*(3.5-1.5)= should give you 8. Without the parentheses, this would 12.5.

Essentially, the left parenthesis comes immediately after an arithmetic operator, and the right parenthesis must close the parenthetical expression right after a number, and an operator must follow the right parenthesis.

This calculator is incapable of displaying simplified fractions (i.e. 1 ½), you will have to use the decimal value or contain your complex fraction in parenthesis. (i.e. (5/2).)

Just follow the order of operations. 1. Parenthesis 2. Exponents 3. Multiply and Divide in order from left to right, and 4. Add and subtract in order from left to right. I'm assuming you are missing the left parenthesis before the 6 (.

(6 + 22) / 2 -12 x 3 =
28 / 2 - 12 x 3 =
14 - 36 =
-22

Each of these are function keys. Press the key and the display will show the name of the function followed by an open parenthesis. Enter a value or expression for the argument and close the parenthesis.
