400 x 800 = 320000. When solving these I find it easiest to work out the problem without the zeros first eg. 4 x 8 = 32 then add the amount of zeros contained in the question so in this example(800x400) 4 zeros so add the amount of zeros(4 zeros) to the basic question answer (32) so therefore equals 320000
