                  This video shows us the rules for adding and subtracting measurements to show our level of accuracy. Note that the rules for addition/subtraction with significant figures are VERY different than the rules for mulitplication/division. Think about which number is the most precise!

                      For a complete lesson on subtracting mixed numbers go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson students learn to subtract mixed numbers by first subtracting the fractions then subtracting the whole numbers. For example to subtract 6 1/3 - 4 2/3 first subtract 1/3 � 2/3. However notice that 1/3 � 2/3 equals a negative fraction. In this situation the first fraction 6 1/3 can be rewritten as 5 + 1 1/3 or 5 + 4/3 or 5 4/3. Therefore the original problem 6 1/3 - 4 2/3 can be rewritten as 5 4/3 - 4 2/3. Now subtract the fractions 4/3 � 2/3 to get 2/3 and subtract the whole numbers 5 �4 to get 1. So 5 4/3 - 4 2/3 = 1 2/3. Note that some of the problems in this lesson also require the student to find a common denominator for the fractions. For example 8 5/16 - 1 1/8.
