That way, if your calculations are way off, you will notice.
It is helpful because when you are finished estimating (for example: multpliying, diving, adding or subtracting) it's like checking your work that's why it can be helpful to estimate before finding the actual product.
because if you estimate it will elp you understand what the problem you are doing.For in example.what is 20 tims 84 so you esitmate near the tens place. my esitmate was 1,600 because 20times 80= 1,600.the real answer is 1,680
Its for a word problem. At least that was I was taught. FIND OUT; What is the problem about,What is the question in the problem,what do I have to find out in order to answer the problem,What info can I start with,Is there any words or ideas that I don't understand, Am I missing needed info. CHOOSE A STRATEGY; Have I solved a problem like this before strategy did I use before, would that strategy be helpful? SOLVE IT Is my math is to read ,was the strategy helpful would another strategy be more helpful? Do i need to multiply divide add or subtract etc
It means that the direction of the vector is that same as before but the magnitude has been changed - by a scalar factor.
400 + 500 = 900
Yes.
yes

It can be helpful for people who do not have a clue where the decimal point should go in the answer. For those who do know, the exercise is pointless.
why am i reading this?
i really don't know this i am the one who asked it and none of these work for me
It was of a high magnitude.They may feel discouraged at the magnitude of the task before them.
Estimating can be helpful before getting an actual answer because it allows you to make quick calculations and get a rough idea of what the final answer might be. It helps in determining if the answer is reasonable or if there might be a mistake in the calculations. Estimating can also save time and effort by giving a sense of whether further calculations are necessary or if the rough estimate is sufficient.
Mr. Kevin thinks that estimation can help students get real sense of conversion between fraction and percentage.
More context is required before the question can be answered.
you must estimate before a problem then you can find out your real answer a compare
