Math Question: This works for everything but 9x1 so anything times nine you just add the numbers your multiplying so for example 9x8 is 72 so you do 9+8 which is 17 so the second number for your adding question is always the number in the tens place except for 9+1and for nine times nine the the sum you get for for the addition equation is going to be the answer to 9 times nine flipped around so for 9+9 just think of flip flops and then flip around your answer to 9+9 which is 18 then you get 81 this only works for equations up to 9x9

Yes, that only works for those equations. That is just a different way to help learn your 9 facts. What can I help you with?
