Given:
\n" ); document.write( ".
\n" ); document.write( "1+2-3*4/5
\n" ); document.write( ".
\n" ); document.write( "By the rules governing the order of operations, the first thing you do in this problem
\n" ); document.write( "is to read it from left to right and perform the multiplications and divisions as you come
\n" ); document.write( "to them.
\n" ); document.write( ".
\n" ); document.write( "The first multiplication or division you come to in going from left to right is -3 times 4
\n" ); document.write( "and this results in -12, and that is followed by the division sign so you divide the -12
\n" ); document.write( "by 5 next. With these two actions you now have simplified the problem to:
\n" ); document.write( ".
\n" ); document.write( "
\n" ); document.write( ".
\n" ); document.write( "and the -12/5 is equal to -2.4. So the problem is reduced to:
\n" ); document.write( ".
\n" ); document.write( "
\n" ); document.write( ".
\n" ); document.write( "Now return to the start of the problem and reading from left to right you do the additions
\n" ); document.write( "and subtractions as you come to them. The first one you come to is 1 + 2 and that reduces
\n" ); document.write( "the problem to:
\n" ); document.write( ".
\n" ); document.write( "
\n" ); document.write( ".
\n" ); document.write( "and finally you subtract 2.4 from 3 to get the answer 0.6
\n" ); document.write( ".
\n" ); document.write( "I put it in decimal form so you could see the flow of the problem. It could also have been
\n" ); document.write( "done in fraction form starting from the result we got above which is:
\n" ); document.write( ".
\n" ); document.write( "
\n" ); document.write( ".
\n" ); document.write( "At this point we go back to the left and reading from left to right we do the additions
\n" ); document.write( "and subtractions beginning with 1 + 2 = 3 which reduces the problem to:
\n" ); document.write( ".
\n" ); document.write( "
\n" ); document.write( ".
\n" ); document.write( "But 3 is equivalent to
\n" ); document.write( ".
\n" ); document.write( "
\n" ); document.write( ".
\n" ); document.write( "Notice that both terms have the common denominator of 5 so we can combine them by subtracting
\n" ); document.write( "their numerators to get:
\n" ); document.write( ".
\n" ); document.write( "
\n" ); document.write( ".
\n" ); document.write( "And notice that if you divide 5 into 3 you get 0.6 which is the same answer that we got by
\n" ); document.write( "doing the problem in decimal form.
\n" ); document.write( ".
\n" ); document.write( "So the answer to this problem is either
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to understand the order of operations for problems that involve
\n" ); document.write( "multiplications, divisions, additions, and subtractions. \n" ); document.write( "
