The calculation is as follows:
60005 + (36006 - 28097) 100 + 105 - (87007 - 679) 400 + 80 ÷ 4 * 5800 - 640 ÷ 2 ÷ 4
= 60005 + (7929) 100 + 105 - (86328) 400 + 80 ÷ 4 * 5800 - 640 ÷ 2 ÷ 4
= 60005 + 792900 + 105 - 34531200 + 80 ÷ 4 * 5800 - 640 ÷ 2 ÷ 4
= 60005 + 792900 + 105 - 34531200 + 20 * 5800 - 320 ÷ 4
= 60005 + 792900 + 105 - 34531200 + 116000 - 80
= 792905 - 34531200 + 115925
= -33738270
So, the final answer is -33738270.
