MULTIPLICATION
I suggest you to remember the tables up to 9 because it saves some valuable time during calculation. Let us look at the case of multiplication by a number more than 10 5892 X 11 05892 X 11 STEP I :(2 X 1) = 2 STEP II :(9 X 1)+2 = 1 12 STEP III :(8 X 1)+9+1 = 1 812 STEP IV :(5 X 1)+8+1 = 1 4812 STEP V :(0 X 1)+5+1 =64812 5324 X 12 05324 X 12 STEP I :(4X 2) =8 STEP II :(2 X 2)+4 =88 STEP III :(3 X 2)+2...
