∙ 9y agoThe 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.

∙ 9y agoI suggest you divide 1437 / 12, round the result to the nearest integer, then multiply by 12 again.
Rounding is when you take a decimal or fraction and make it the closest whole number. If the number you are rounding is five or higher round up and if it's four or below round down. For instance, 7.2 rounds down to 7, 6.8 rounds up to 7.
21 ^^
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
You can not have a whole number of the decimal, unless you want to round the number to the closest whole number, in which case would be 1.
To estimate, you round the number to the nearest 10 and add, subtract, divide, or multiply. If the number is a decimal (ex. 12.132), you would round it to 12, and then round that to 10.

83x29 is estimated to 2410 if you round it up.
58 if your trying to round up.
The number 1 is the closest whole number to 1.283.

Your estimate will be greater than the exact number.
You look at the number on the right closest to the decimal and if it is 5 or greater round up and if it is 4 or lower round down. In this case, 38 is the answer.

3 because you round 3.14 down. :)
