465*463/464怎么简便运算
465*463/464
=465*(1-1/464)
=465*1-465*1/464
=465-465/464
=465-2+463/464
=463又463/464

(465×463)/464
=((464+1)×(464-1))/464
=(464²-1)/464
=464-1/464
=463又463/464

(464+1)*(464-1)/464

(464+1)x463/464=463+463/464=463又463/464

465*463/464
=(464+1)*463/464
=464*463/464+463/464
=463又463/464

【(464+1)/464】*【(464-1)/464】
=【1+1/464】*【1-1/464】
=1-(1/464)^2

465*463/464=(464+1)*463/464=463+463/464=463+(1-1/464)=464-1/464

465*463/464=(464+1)*(464/-1)/464=464-1/464
