Other Tips on Remembering 4 x 9 = 36
Double-Double
Double-double the number you are multiplying four by. (Double
it twice)
4 x 9 (Double 9 Twice)
9 doubled once is 18, 18 doubled is 36
Another way to figure the answer is double the answer you would
get if you multiplied the number by 2.
9 x 2 = 18
18 x 2 = 36
