简便计算方法101*44=(100+1)*44=100*44+1*44=4400+44=4444
原式=44x101-44x1=44x(101-1)=44x100=4400
44*101=44*(100+1)=4400+44=4444
44+44x101-44x2=44x(1+101-2)=44x100=4400
41*101=41*(100+1)=41*100+41*1=4100+41=4141
45x101一101=(45-1)*101=44*101=44*(100+1)=4400+44=4444
4.9*101=4.9*(100+1)=490+4.9=494.9或:4.9*101=(5-0.1*101=505-10.1=494.9
101*44+35*101+101*22-101=101*(44+35+22-1)=101*100=10100
=44x101-44=44x101-44X1=44x(101-1)=44x100=4400
44X123-44X22-44X101=44X(123-22-101)=44X 0=0
