a strategy you could use is add up 3208 four times getting
3208+3208
and then 6416+3208
getting 9264+3208
ending up with 12832

Well I mean another strategy is

32 x 4 = 128

Add nothing for the 0 because 4 x 0 is 0.

128

The multiply 4 x 8 = 32.

Then add 32 at the end of 128.

12,832.

This is very complicated and probably will not work on an average problem, but it is a strategy I use for not as complex problems.
