用简便计算:(-5.35)*(-3)+5.35*(-7)+5.35*4用简便计算:(-5.35)*(-3)+5.35*(-7)+5.35*4用简便计算:(-5.35)*(-3)+5.35*(-7)+5

用简便计算:(-5.35)*(-3)+5.35*(-7)+5.35*4
用简便计算:(-5.35)*(-3)+5.35*(-7)+5.35*4

用简便计算:(-5.35)*(-3)+5.35*(-7)+5.35*4
(-5.35)*(-3)+5.35*(-7)+5.35*4=5.35*(3)+5.35*(-7)+5.35*4
=5.35*(3-7+4)
=0

:(-5.35)×(-3)+5.35×(-7)+5.35×4
=:5.35×3+5.35×(-7)+5.35×4
=5.35×(3-7+4)
=5.35×0
=0
