lgnoring whether the first number is larger or smaller than the second,the number of cobinations is 4 x 3 x 2 x 1 = 24.

half of these will have the first number larger than the second,and half will be the other way around.so there are 12 combinations

to make the total large as possible,the large digits should have place value as large as possible.that is , 9 and 8 will be in the tens positions of the two numbers.

Then 3 and 2 will be in the units positions.

Then the sum is either  93 + 82 = 175 or 92 + 83 = 175,both with total 175
