100 - 1 = 99.
100-1-1-1= 99-1-1= 98-1= 97 ..... ..... ..... ..... ..... ..... ..... ..... 100-1-1-1= 100-3= 97
It is: 132 minus 99 = 33
(220 of them) minus (the smallest 99) = 121
1,000 minus 99 is 901.
100 - 1 = 99.
1002 - 992 = (100+99)(100-99) = 199x1 =199
100 minus 1 = 99
Take away 100 and add one...
100-1-1-1= 99-1-1= 98-1= 97 ..... ..... ..... ..... ..... ..... ..... ..... 100-1-1-1= 100-3= 97
It is: 132 minus 99 = 33
(220 of them) minus (the smallest 99) = 121
1,000 minus 99 is 901.
this is the same as asking 375 minus 99, very easy, 375-100=275+1=276
108 - 99 = 9
111 minus 99 is 12.
1001 - 99 = 902
