Quasim ordered 32 cases with 28 cans of fruit in each case. he also received 24 cases with 13 large cans of fruit in each case. how many more small cans of fruits does he have ?

I am assuming the 32 cases contain the small cans...

32 cases...with 28 small cans of fruit in each case..
32 * 28 = 896 small cans of fruit in total

24 cases...with 13 large cans of fruit in each case...
24 * 13 = 312 large cans of fruit in total

so there are (896 - 312) = 584 more small cans then large cans <==
