小学四年数学用简便方式计算44*75
44*75
=(11x4)x(25x3)
=(4x25)x(11x3)
=100x33
=3300

(40+4)*(100-25)=40*100-40*25+4*100-4*25=3300

44*75
=(11*4)*(3*25)
=(25*4)*(11*3)
=100*33
=3300
望采纳

分解质因数,简单

44*75=(50-6)*75=50*75—6*75=3750-450=3300

(40+4)*75=40*75+4*75=3000+300=3300

44x75
=(4x75)+(40x75)
= 150+1500
= 1650

22*2*15*5

44*75
=44*(70+5)
=44*70+44*5
=3080+220
=3300

44 x 75
=(11x4)x(25x3)
=(4x25)x(11x3)
=100x33
=3300

44*75
=(4*11)*(3*25)
=4*25*(11*3)
=100*33
=3300

44x75
=(11x4)x(25x3)
=(4x25)x(11x3)
=100x33
=3300
望采纳,谢谢!

44*75
=11*4*75
=11*300
=3300

44*75
=(22*2)*(25*3)
=(22*25)*(2*3)
=550*6=3300
