Because you will see that the sum or difference is close to your estimate. If it isn't that close, round the number you're estimating to the nearest compatible number and find the sum or difference
Sum = Addition
Difference = Subtraction
Product = Multiplication
Quotient = Division
Does this answer help?
Because you should always guess first and you don’t have to be right
So that you can see if your answer is close to the actual answer
No you can check your awnser

The sum or the difference between two irrational numbers could either be rational or irrational, however, it should be a real number.
Calculate the difference between each number and the next number. Write them down. It should be quite obvious from there.
The idea is to round both numbers to the nearest multiple of 10 (in this case), then multiply. After rounding, you should be able to do the multiplication in your head - but if you have trouble with that, try to do it with pencil and paper first.
There should be a negative button on your calculator, separate from the minus button. Press that button before pressing the buttons for the numbers of the exponent.
You could add 13.

Maths Teachers ask students to estimte the sums of large numbers before they actually solve the solution because students that do this regularly will eventually become very accurate and will soon be able to guess the entire problem correctly without any working out. Estimating is a very good learning technique and is very effiecient! Hope this helps!

Whole numbers are rational numbers with a denominator of 1. The difference with general rational numbers is that the denominators are likely to be different and they must be made the same by converting the fractions into equivalent fractions with the same denominator before the addition can be done - by adding the numerators and keeping the denominator, and simplifying (if possible) the result. With whole numbers the denominators are already the same (as 1) and so the addition can be done straight away.
If you are using the above numbers in a subtraction equation, the difference is 1900, i.e 3057 minus 1157 equals 1900. You can check this is correct by adding 1900 to 1157, your answer should be the original 3057. If you mean literally the difference is the numbers 30 & 11
One important notice that should be considered about the difference between the median and the average is the time required to perform both. As the median requires sorting the numbers before finding its centered value of the list, this takes much more time either manually or by computer
Whatever you feel like it makes no difference.
