Solution QR Code JIS X 0510 Creator In None Using Barcode maker for Software Control to generate, create QR Code JIS X 0510 image in Software applications. Recognizing QR In None Using Barcode scanner for Software Control to read, scan read, scan image in Software applications. We can break this down stepbystep, paying careful attention to signs and using parentheses when we need them Here we go: 5 + ( 3) = 5 3 = 2 2 ( 6) = 2 + 6 = 8 8 10 = 2 2 + 14 = 12 12 ( 21) = 12 + 21 = 33 Drawing QR In C#.NET Using Barcode encoder for VS .NET Control to generate, create QR Code image in VS .NET applications. Making QRCode In VS .NET Using Barcode creator for ASP.NET Control to generate, create QRCode image in ASP.NET applications. The Commutative Law for Addition
Paint QR Code In .NET Using Barcode creation for .NET Control to generate, create QR Code JIS X 0510 image in Visual Studio .NET applications. Making QR In VB.NET Using Barcode generation for VS .NET Control to generate, create QRCode image in .NET applications. In basic arithmetic, you learned that you can add a long string of numbers backward or forward, and it doesn t matter Good accountants take advantage of this when checking their work They ll add up a column of numbers from top to bottom, then again from bottom to top, just to be sure they have done the arithmetic correctly Bar Code Encoder In None Using Barcode maker for Software Control to generate, create barcode image in Software applications. GS1  12 Creator In None Using Barcode generator for Software Control to generate, create Universal Product Code version A image in Software applications. It works when you add The fact that you can add two integers in either order and get the same result is called the commutative law for addition It means you can commute (interchange) the two numbers you re adding, called the addends, and get the same sum either way In formal terms, a mathematician would say that for any two integers a and b, EAN13 Drawer In None Using Barcode creator for Software Control to generate, create EAN13 image in Software applications. Painting Barcode In None Using Barcode generator for Software Control to generate, create barcode image in Software applications. a+b=b+a This works whether the numbers are positive, negative, or 0 It also works if there are three, four, five, or more numbers in a sum, as long as the number of addends is not infinite Make Code 39 In None Using Barcode generation for Software Control to generate, create Code39 image in Software applications. DataMatrix Generator In None Using Barcode drawer for Software Control to generate, create ECC200 image in Software applications. It fails when you subtract In subtraction, the order does matter It s easy to find an example that shows why Consider this: Printing UPC  8 In None Using Barcode generator for Software Control to generate, create EAN8 image in Software applications. Encode Data Matrix 2d Barcode In ObjectiveC Using Barcode maker for iPad Control to generate, create Data Matrix ECC200 image in iPad applications. 3 5 = 2 Make Barcode In Visual Basic .NET Using Barcode encoder for .NET framework Control to generate, create barcode image in VS .NET applications. Generate UCC  12 In Visual Studio .NET Using Barcode printer for ASP.NET Control to generate, create GTIN  12 image in ASP.NET applications. 58 Addition and Subtraction
Code 3 Of 9 Scanner In .NET Framework Using Barcode reader for .NET Control to read, scan read, scan image in .NET applications. Bar Code Creation In .NET Using Barcode maker for ASP.NET Control to generate, create barcode image in ASP.NET applications. but 5 3=2 In formal terms we would say that for any two integers a and b, it is not always true that a b=b a In fact, it is almost never true It only works if a and b happen to be the same European Article Number 13 Decoder In Java Using Barcode recognizer for Java Control to read, scan read, scan image in Java applications. Read Bar Code In Visual C#.NET Using Barcode scanner for Visual Studio .NET Control to read, scan read, scan image in .NET framework applications. Turning it insideout We can use a trick that will make the commutative law sort of work with subtraction This trick is often used by accountants who must work with long columns of credits (money added) mixed with debits (money taken away) This trick involves taking every subtraction and turning it into the addition of a negative number Remember that adding a negative is the same as subtracting a positive That is, for any two integers a and b, a b = a + ( b) Because the righthand side of this equation is an addition problem, we can apply the commutative law and get a + ( b) = b + a Now we can combine the above two equations into a threeway equation: a b = a + ( b) = b + a Then we can get rid of the middle term and write a b = b + a Let s call this the insideout commutative law for subtraction That s not a formal name, but you might find it useful as a memory aid Are you confused
Imagine that you have a checking account and your balance on January 1 was exactly $700 Consider that as a starting deposit By the end of June, you ve made 15 deposits and written 20 checks You want to figure out your balance as of June 30 You convert all the checks to negative deposits For example, a check for $25 becomes a negative deposit of $25 Now you can add all the positive deposits and negative deposits in any order, and you ll always end up with the same final balance if you don t make any calculation errors! The Associative Law for Addition
Here s a challenge! Suppose you have bought a new car and you want to go for a test drive You live on a flat plain that seems to stretch forever in all directions You start driving on a straight highway that runs north and south for hundreds of miles on either side of your home town You drive 25 miles north, then turn around and drive 45 miles south Then you turn around again, driving 50 miles north Then you go 7 miles south, 12 miles north, 49 miles south, and finally 5 more miles south How far from your home town, and it what direction, will you finish Solve this problem in two different ways
