i need to learn my multiplication tables at least up to 9 and i have to do it fast because i'm in 8th grade and i don't know what they are. how do i learn them fast??

There are all kinds of tricks but in the end you just plain have to practice. Flash cards help.

An good hint for memorizing the 9's in multiplication tables are: the product/total's two digits will always add up to nine.
Ex: 9*4=36 ... 3+6=9
Also, when you multiply a number by nine, the product will always be one lower than that digit you just multiplied by (not nine).
See above ex. 9*4=36 .... 3 is one less than 4
Hope this helps!
