10^2-10^0=100-1=99
10^3-10^0=1000-1=999
10^3+10^2=1000+100=1100
10^4-10^3=10000-1000=9000
10^5-10^2==100000-100=99900
10^3+10^2=1000+100=1100
10^2-10^0=10(10-1)=90
10^3+10^2=10^2(10-1)=100(10-1)=900
10^4-10^3=10^3(10-1)=1000(10-1)=9000
10^5-10^2=10^2(10^3-1)=100(1000-1)=99900
10^3+10^2=10^2(10-1)=100(10-1)=900
