72*26+36*48的简便算试
72*26+36*48的简便算试

72*26+36*48的简便算试
72=36*2
所以
原式=36*2*26+36*48
=36*(52+48)
=36*100
=3600

72*26+36*48
=2x36x26+36x48
=36x(2x26+48)
=36x(52+48)
=3600

72*26+36*48
=36*52+36*48
=36*(52+48)
=36*100
=3600

36*(26*2+48)=36*100=3600

72*26+36*48
=2*36*26+36*48
=36*(2*26+48)
=36*100
=3600

72*26=36*52

72=36*2
原式=36*(2*26)+36*48=36*(52+48)=3600

72*26+36*48
=2*36*26+36*48
=36*(52+48)
=36*100=3600
