18×(82-147)-82×(18+147)
\(18\times\left(82-147\right)-82\times\left(18+147\right)\)
\(=18\times82-18\times147-82\times18-82\times147\)
\(=\left(18\times82-82\times18\right)-147\times\left(18+82\right)\)
\(=-147\times100\)
\(=-14700\)
\(18\times\left(82-147\right)-82\times\left(18+147\right)\))
=\(18\times82-147\times18-18\times82-147\times82\)
=\(-147\times\left(82+18\right)\)
=\(-147\times100\)

-25.(35+147)+35.(25+147)
-25.(35+147)+35.(25+147)
= -25.35 + (-25).147 + 35.25 + 35.147
= 35.(-25+25) + 147.(-25+35)
= 35.0 + 147.10
= 0+1470

Tính: 3972×(3962-147)-3962×(3972-147)
3972×(3962-147)-3962×(3972-147)
= 3972 x 3962 - 147 - 3962 x 3972 - 147
= 147 x [(3972-3972)-(3962-3962)]
= 147 x [ 0 - 0 ]
= 147 x 0
