Question

132*45+168*79+132*34简便计算？

Answer 1

132*45+168*79+132*34
=132*45+132*34+168*79
=132*(45+34)+168*79
=132*79+168*79
=79*(132+168)
=79*300
=(80-1)*300
=80*300-1*300
=24000-300
=23700

Answer 2

132×45+168×79+132×34
=132×45+132×34+168×79
=132×（45+34）+168×79
=132×79+168×79
=（132+168）×79
=300×79
=300×（80-1）
=300×80-300
=24000-300
=23700

Answer 3

＝(132*45+132*34）+168*79
＝132*79+168*79
＝79*（132+168）
＝79*300
＝23700

Answer 4

132×45+168×79+132×34
=132×45+132×34+168×79
=132×（45+34）+168×79
=132×79+168×79
=79×（132+168）
=79×300
=23700
