So if someone asked you to write down the value of pi to two decimal places, would you write out 3141?Evaluate (0.86)6 to 4 decimal places.
If I punch this into my calculator I get, 0.4045672351 so I should put 40456?
The plus sign is not required, although x+y is a binomial expression, as you say.(x)(y) x/y are not binomial because there isn't + between the x and y.
Because x-y is also a binomial?The plus sign is not required, although x+y is a binomial expression, as you say.
Evaluate (0.86)6 to 4 decimal places.
If I punch this into my calculator I get, 0.4045672351 so I should put 40456?
Not to be rude, but didn't you ever learn this in school?so, can someone tell me how this will be rounded up?

I am grateful for your help, however I am not being rude when I say a question is only easy when you know the answer.....Not to be rude, but didn't you ever learn this in school?
In order to round to x decimal places you look at the next digit beyond it (to the right). If it's less than 5, then round down, meaning leave the x digit as is. If the next digit is 5 or higher though, you round x up to the next digit.
Example:
Round 63.9548 to 3 decimal places
Look at the 3rd decimal place (4). Then look at the digit beyond it (8). Since 8 is higher than 5, then you need to round x up one digit, so the 4 becomes 5. Therefore, 63.9548 rounded to 3 decimal places is 63.955.
Understand?
Not sure why you are offering anything if you are going to be that rude, apologies I made a mistake.Before you learn to round up, what about counting?
You are asked for 4 decimal places, so why are you offering 5?
Unfortunatley I am being taught to pass rather than taught! Sad state of the times. Hence the reason I am staying up to god knows what hour every night trailing forums reading and teaching myself!Would you agree that someone that has not learned (for whatever reason) how to tighten a right-handed nut is probably not at a point where they should be attempting to rebuild an automatic transmission?
Math is the same way. There are layers and layers of skills that, by and large, build upon one another. While there's certainly some flexibility at the margins of what order skills are mastered in, if you get too far ahead of yourself you are likely to hit a brick wall at some point -- hard.
Learning how to round a result to N decimal places fits into one point in the math progression and learning how to exponentiate fits into another. Those two points are far enough apart that someone that hasn't yet learned (for whatever reason) to round a result to N decimal places is almost certainly not properly prepared to master exponentiation. Not because rounding is critical to exponentiation, but because it is an indicator (and not a perfect one, by any means) of where your general level of skill mastery sits.
You yourself gave a big hint to what is likely the underlying problem -- you are just learning to plug numbers into a calculator and taking whatever it spits out. You are not alone. The problem is that this creates, at best, an illusion that you know how to do something and, sooner or later, that illusion will no longer suffice and you will hit a brick wall -- hard.
Sadly, in many schools in many parts of the world (with the so-called "developed" world probably being the worst) the basic skills are seen as "beneath" us (after all, the reasoning goes, we'll never be far from a computer or calculator) and so mastery of them is not expected and many of the skills themselves aren't even presented or, if they are, only in passing. Unfortunately, this means that students are left to deal with mastering them only after they hit that brick wall -- hard enough to bring it to their attention.
I certainly understand your point, but you seem to have missed mine. Please don't take this the wrong way, I mean no offense, but are you by any chance still in grade school and learning this for the first time? That would make a lot more sense. Most of the members here are used to college-age and up who usually have done this sort of thing many times before. If you are younger, however, I think we all would have a much better understanding of where you are and how to best help you.I am grateful for your help, however I am not being rude when I say a question is only easy when you know the answer.....
Yes, sad times and it's not an easy road to travel -- so hat's off to you for making the effort (when most don't).Unfortunatley I am being taught to pass rather than taught! Sad state of the times.
