Subtracting Integers Using Algebra Tiles
 Subtracting Integers Using Algebra Tiles4 - (-5) = ? If you have enough to takeaway, subtraction ofintegers is easy!-5  - (-3) = ?Take AwaySo -5 - (-3) = -2 8 - 3 =-10 - (-2) =40 - 13  =-100 - (-25) =-53.4 - (-3.4) =Practice Taking Away: By adding zero pairs,the number does not change!Can't Take Away?Use Zero Pairs4 - (-5) = ? By adding zero pairs,the number does not change!Can't Take Away?Use Zero Pairs4 - (-5) = ?zero pairs Now take away4 - (-5) = Can't Take Away?Use Zero Pairs4 - (-5) = ?zero pairs is the same as:Notice:4 - (-5) = 4 + 5 = Can't Take Away?Use Zero Pairs4 - (-5) = ?zero pairs Can't Take Away?Use Zero Pairs-4 - 4 = ? Can't Take Away?Use Zero Pairs-4 - 4 = ?zero pairs -4 + (-4) =-4 - 4 =Can't Take Away?Use Zero Pairs-4 - 4 = ?zero pairs Can't Take Away?Use Zero Pairs2 - 5 = ?zero pairs 2 + (-5) =2 - 5 =Can't Take Away?Use Zero Pairs2 - 5 = ?zero pairs -1 - (-3) = ?Can't Take Away?Use Zero Pairs -1 - (-3) =-1 + 3 =-1 - (-3) = ?Can't Take Away?Use Zero Pairszero pairs
