4*4*4-{[(-3)*(-3)*(-3)*(-3)]-[(-1)/2.5+2.25*(-4)]/(24.53-27.53)}4*4*4-{[(-3)*(-3)*(-3)*(-3)]-[(-1)/2
4*4*4-{[(-3)*(-3)*(-3)*(-3)]-[(-1)/2.5+2.25*(-4)]/(24.53-27.53)}
4*4*4-{[(-3)*(-3)*(-3)*(-3)]-[(-1)/2.5+2.25*(-4)]/(24.53-27.53)}
4*4*4-{[(-3)*(-3)*(-3)*(-3)]-[(-1)/2.5+2.25*(-4)]/(24.53-27.53)}
原式=4×4×4－{[(-3)×(-3)×(-3)×(-3)]－[(-1)÷2.5＋2.25×(-4)]÷(24.53－27.53)}
=64-{(+81)-[(-1)×0.4+(-9)]÷(-3)}
=64-[+81-3.6÷(-3)]
=64-[+81-(-1.2)]
=64-(+82.2)
=64-82.2
=-18.2
