Re: Help!!!!!!!!
7x6 = 6x7
7x8 = 8x7
If you know one of them then you know both of them! As for 8x8, you have to learn it!

Re: Help!!!!!!!!
Yes, the squares mean that you actually have to learn a little more than half.
To know the tables up to 10x10, you need to learn 55 numbers.
Of course, since some of them are very simple (like the 1- or 10-times tables), the amount you have to put any effort into learning is less than that.
Why did the vector cross the road?
It wanted to be normal.
