Algebra.Com's Answer #28436 by tutorcecilia(2152)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "You will need to apply the order of operations which is the order in which a problem is solved. The abbreviation P.E.M.D.A.S. will give you the correct order to follow: \n" ); document.write( "P = Parenthesis first \n" ); document.write( "E = Exponents or radicals next \n" ); document.write( "M or D = Multiplication or Division (whichever comes first) \n" ); document.write( "A or S = Addition or Subtraction (whichever comes first) \n" ); document.write( ". \n" ); document.write( "Starting from left to right, you should see that this problem only involves three operations: subtraction, addition, and division. To make it easier, convert the fraction to a decimal.: \n" ); document.write( "4- (-3) + 0.50 - 2/-2 \n" ); document.write( ". \n" ); document.write( "According to PEMDAS, perform addition or subtraction in the order in which it occurs. The subtraction was changed to addition using the rules for adding or subtracting integers*: \n" ); document.write( "4+3+0.50-2/-2 \n" ); document.write( "7+.50-2/-2 \n" ); document.write( "7.50-2/-2 \n" ); document.write( "5.50/-2 \n" ); document.write( ". \n" ); document.write( "Next, perform multiplication or division which ever occurs first. Since there is no multiplication, divide: \n" ); document.write( "5.50/-2 \n" ); document.write( "-2.75 \n" ); document.write( ". \n" ); document.write( "*Rules for adding or subtracting integers: \n" ); document.write( "When adding integers with the same sign (both negative or both positive), add the absolute values and take the common sign. \n" ); document.write( "When adding integers with different signs (one is positive and the other is negative), subtract the absolute values and take the sign of the larger integer. \n" ); document.write( "When subtracting, change the operation to addition and change the sign of the second integer. Than follow the rules of adding integers. \n" ); document.write( "Example: 4-(-3)= 4+ (+3) = +7\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
