36✖️45➖35✖️46
=(35+1)x45 - 35x(45+1)
=35x45 +45 -35x45-35
【第一、第三项抵消】
=10
解: 36X45-35X46
=(35+1)x45-35x(45+1)
=35x45+1x45-35x45-35x1
=35x45+45-35x45-35
=45x(35+1-35)-35
=45x1-35
=45-35
=10
36×45-35×46
=36×45-35×45-35
=(36-35)×45-35
=45-35
=10
=36*46-36-36*46+46
=-36+46=10
答:
36*45-35*46
=(35*45+45)-(35*45+35)
=45-35
=10
