I've never been that great at math but I survived all the way through college by using the easy ones and then going from there.
For example, If I'm at a resturant and I want to give someone an 18% tip on a 16.53 meal...this is how I figure it out:
10% of 16.53 is 1.65 $1.65
Half of a dollar and sixty five is about .83 cents
That's 15 % at 2.48 and then I'll add 3 1%s (.16 + .16 + .17) (.59)
18% of 16.53 is $3.07.
I know that's weird but once you get used to it, mental multiplication comes easier and easier.
repeating them over and over again
i hate it but use flash cards
Those basic multiplication tables is the only way I can think of. Try studying a multiplication table and then taking some timed tests. Good luck!
Memorize the multiplication tables (at least up to 10 x 10). It's easy. It's fast. It's effective. It's my personal opinion.
learn the easy numbers first. like start with 5's. and an easy method is to do it like this:
2's and 10's are also very easy. Once you master the easy numbers try to excel at a difficult one each week. maybe one week you can practice 7's the next week you can practice 8's. You have to do it outside of class too though, because you don't have enough time in school to really get good at it.
here is a neat way to multiply 9's also.
9x1 = 09
9x2 = 18
9x3 = 27
9x4 = 36
9x5 = 45
do you see the pattern? look at the first digit of each number! it goes in order from 0 to 4..now look at the second digit in each number! They count down instead! Keep going with the 9's and you'll see that the pattern stays the same! Good luck!
