8,000 minus 165 is 7,835.
8000 − 598 = 7402
8000-500=7500.
8,000 minus 900 is 7,100.
-165
x2-4x-165 = (x-15)(x+11) when factored
8000 - 30 = 7,970
24,000 − 8,000 = 16,000
181 - 16 = 165
8/11 - 4/15 = 120/165 - 44/165 = 76/165 which cannot be simplified.
76/165
8000 - 2009 = 5991 also minus 1 because there was no year 0 so it was 5990 BC BC = Before Christ
