简算55×102-110
55×102-110=55×2×51-110=110×51-110=110×(51-1)=110×50=5500

=55×102-55×2
=55×(102-2)
=55×100
=5500

55×102-55×2
=55×(102-2)
=55×100
=5500

原式=5×11×102-11×10=11×(5×102-10)=11×500=5500

=55×(102-2)=5500

55X102-55X2=55X(102-2)=5500

5500

55x102-110
= 55X100 + 55X2 -110
=5500+110-110
=5500

5500

55*102-110=55*100+55*2-110=5500+110-110=5500

55×100+(55×2-110)=5500

55×102-110
55×102-55×2
55×(102-2)
55×100
5500

原式=55×(100+2)-110
=55×100+55×2-110
=5500+110-110
=5500

=55×102-55×2=55×(102-2)=55×100=5500

=55×102-55×2
=55×(102-2)
=55×100
=5500

=55*102-55*2
=55*100
=5500

=55×102-55×2
=55×(102-2)
=55×100
=5500
