20162016 - 20152015
= 2016 x 10001 - 2015 x 10001
= 10001 x (2016 - 2015)
= 10001 x 1
= 10001
Tính nhanh 20162016 - 20152015
20162016 - 20152015
= 2016 x 10001 - 2015 x 10001
= 10001 x (2016 - 2015)
= 10001 x 1
= 10001
\(20162016-20152015=2016.10001-2015.10001\)
\(=10001\left(2016-2015\right)\)
\(=10001.1\)
\(=10001\)
20162016 - 20152015
