80 minus 4 is 76.
They are: 8 minus 4 = 4
80 minus 12.6 is 67.4
90 - 80 = 10
-80 - 1 = -81
140 - 80 = 60
80 - 45 = 35
5000.00 minus 20% = 80% of 5000.00 = 5000.00*80/100 = 4000.00
173 - 90 = 80
200
No. 80 000 minus 8 is not 10 000 but it is 79 992.
To factorise x3 + 5x2 - 16x - 80 I note that -80 = 5 x -16 and 5 & -16 are the coefficients of x2 and x. Thus I have: x3 + 5x2 - 16x - 80 = (x + 5)(x2 - 16) and the second term is a difference of 2 squares, meaning I have: x3 + 5x2 - 16x - 80 = (x + 5)(x + 4)(x - 4)
an A minus obviously ranges from an 80 to a 84 :D
