Question

123×67-23×67+33×82+33×18等于多少简便计算？

Answer 1

123×67-23×67+33×82+33×18
=(123-23)x67+33x(82+18)
=100x67+33x100
=100x(67+33)
=100x100
=10000

Answer 2

123×67-23×67+33×82+33×18
＝67×(123-23)+33×(82+18)
＝67×100+33×100
＝(67+33)×100
＝100×100
＝10000

Answer 3

123*67-23*67+33*82+33*18
=67×（123-23）+33×（82+18）
=67*100+33*100
=6700+3300
=10000

Answer 4

123×67—23×67+33×82+33×18
＝67×（123—23）+33×（82+18）
＝67×100+33×100
＝（67+33）×100
＝100×100
＝10000

Answer 5

123×67－23×67+33×82+33×18
=67×（123－23）+33×（82+18）
=67×100+33×100
=6700+3300
=10000
