70-45=25
45 x 89 = 4,005
45 x 6 = 270
The way that I remembered multiples of 9 is that whatever you're multiplying by you can put that finger down and the fingers left will be the answer... Such as.. You're multiplying 9 x 5. Well put your 5th finger down (thumb on left hand) and then you have 4 fingers on the left hand left and 5 on the right hand. Your answer is 45. 9 x 5 = 45. This process works with all multiples of 9.
