useless for anything less than 80*80ish because you would end up multiplying double digits anyway
ex: 78*75
22+25=
22*25=

why have i wasted 15 minutes of my life on this ._.

The method I use for numbers lower or higher than that is also pretty easy, even if it looks a bit complicated before you try it yourself:
Let's try 147*221:

210
------
147
221

The last digit of every number matches the 0, the second one from the right matches the 1, and so on, increasing by 1 the further you go to the left
Now you multiply all numbers possible with a summed up indicator of 0 (in this case it's only the last digits of both numbers as only 0+0=0) and add the results. In this case it's just 7*1=7 which is the last digit of the result. Now you do the same thing for every number up to 4 (as the highest digit of both numbers has an indicator of 2 and 2+2=4):
xxxx7 (result until now)
next digit: 4*1+7*2=18 (indicators 1+0=1 and 0+1=1)
write down the 8, remember the 1:
xxx87, +1 remembered
next digit: 1+1*1+4*2+7*2=24 (remainder of the last result, 2+0=2, 1+1=2, 0+2=2)
xx487, +2 remembered
next one: 2+1*2+4*2=12 (remainder, 2+1=3, 1+2=3)
x2487, +1 remembered
last one: 1+1*2=3 (remainder, 2+2=4)
Result: 32487

Sorry for my bad english, this made it look far more complicated than it had to be

1*1 =

99+99 = 198
99*99 = 9801

I've always done it like this. Let's say 60*35
60*30= 1800
60*5=300
1800+300=2100
I know this is an easy example but it's helpful when you have scratch paper.
