Overview:<\/strong><\/p>\n Estimation is an important skill in mathematics, because sometimes an approximate figure is needed in everyday life.\u00a0 Suppose a person is deciding if they have enough money to buy all the items on a shopping list or how many materials will be needed to finish a project.\u00a0 Types of estimation include rounding up, rounding down, and rounding to the nearest.<\/p>\n Why Estimate?<\/strong><\/p>\n Estimates are often used when an exact value is not available yet.\u00a0 Suppose that a new road is being built.\u00a0 Before companies can bid on the job, they will need to make an estimate of how much materials and labor will cost to build it.\u00a0 Similarly, if people are going on a journey, they will need to estimate how much money they will need for the trip, as well as anything they might want to pack.\u00a0 Also, sometimes estimates are easier to work with than exact figures.<\/p>\n What Is Rounding Up?<\/strong><\/p>\n Many estimates involve \u201crounding up\u201d.\u00a0 Suppose the calculation for how many hours an individual works monthly shows that they will work 94.6 hours in the next month.\u00a0 As this is only an estimate of how many hours they will work, it is usually rounded up to the next whole number.\u00a0 They will work about 95 hours in the next month. Many small objects, such as pens, pencils, and paper clips are sold in boxes rather than individually.\u00a0 If pens are sold is packages of 25, there will need to be at least 2 packages for a class of 42 students.<\/p>\n What Is Rounding Down?<\/strong><\/p>\n Rounding down is a form of estimation where part of the amount is not taken into consideration.\u00a0 For example, if the interest on a savings account is rounded down to the nearest cent, and the calculated interest is $15.242, only $15.24 would be paid out in interest.\u00a0 Similarly, many calculators truncate any numbers past the 10th<\/sup> decimal place, so that a decimal such as .1236789452 would be read as .123678945.\u00a0The directions that come with calculators tell how many places they will show.<\/p>\n What Is Rounding to the Nearest?<\/strong><\/p>\n Usually when rounding numbers either up or down, more directions are given.\u00a0The distance between the earth and the sun is 92,955, 807 miles.\u00a0It is often rounded to the nearest million, or 93 million miles.\u00a0Suppose the distance from the earth and the sun were given to the nearest 10 miles.\u00a0 It would be rounded to 92,955, 810 miles.\u00a0 Suppose it were given to the nearest 100 miles.\u00a0Then the estimate would be 92, 955, 800 miles.<\/p>\n Interested in pre-algebra tutoring services<\/a>?
