  • Remember the FOURs as a double-double
    • Double-double the number you are multiplying four by.  (Double it twice)
      • 4 x 3  (Double 3 twice)
        • 3 doubled is 6, 6 doubled is 12 
      • 4 x 6 (Double 6 twice)
        • 6 doubled is 12, 12 doubled is 24)
    • Another way to figure the answer is double the answer you would get if you multiplied the number by 2.
      • 4 x 3 (Double the 2 x 3 answer) 
        • The answer to 3 x 2 = 6
        • Double the 6 to get 12
      • 4 x 6 (Double the 2 x 6 answer)
        • The answer to 2 x 6 = 12
        • Double the 12 to get 24
