An estimate is an educated guess.
Approximate and round off mean "about".
An Estimate is basically a guess. Rounding is when you have an answer and you shorten the answer to a given number of digits. eg $27482 would round to $27500 to the nearest hundred dollars.
No, 'estimate' means to guess the value of something, while 'round' means either circular or is a process for truncating a value to fewer significant figures.
A pie chart is round, and a bar graph is square with the bars running either horizontal or verticle.
first round off the two numbers you are dividing to the nearest one. For example 9.5/1.5, round it off to 10/2 which will equal to 5.
A pie chart is round with "slices" to identify data items. A column chart is a series of columns to identify data items. A pie chart allows you to see how all the parts fit into the whole. A column chart allows you to compare all the parts with each other.
Round down both multiplicands and get approximate answer = A. Round up both multiplicands and get approximate answer = B. The true answer is between A and B.
Estimate each difference means to estimate the numbers that they give you estimate means round to the nearest 10 like if 24 and you have to round it it will be 20 if the number is 25 which is in the middle than it will be the number upper which is 30

Round is circular. Around means ' in the vicinity of'. Or used as an estimate Examples : The ball is round. That boy is always hanging around my sister. The bill for the meal will be around £25.
round off each of the numbers and add together: 114 + 257 is about 110 + 260 = 370. Exactly how you round off or approximate the numbers depends on how good you need the estimate to be.
The approx difference is 0.7
The general idea is to quickly get an approximate answer - in a way that you can do much of the calculations, or all of them, in your head.

The only difference is the size (diameter) of the pan.
In arithmetic, estimate usually means rounding the numbers so they're easier to manipulate. Example: Estimate the sum of 432 and 267. You can round them to 430 and 270 and estimate the sum as 700. You could also round them to 400 and 300 and estimate the same total. To estimate a difference, just subtract them. 430 minus 270 is 160. The actual sum is 699 and the actual difference is 165, so your estimates came pretty close.
