B (=8 B (==8 B (===8 B==8 B8 B==8 B (===8 B8 B==8 B (===8 B8 excel 函数=SUM((SUMIFS(Z:Z,B:B,"签约",V:V,">"&B8-1,V:V," =sum(1/countif(B8:K9,B8:K9)) 若a+b=5，ab=6，则：①a4+b4=______；a8+b8=______． 公式“=(YEAR(TODAY())-YEAR(B8))*12+(MONTH(TODAY())-MONTH(B8))-1 如何理解excel数组公式 {=sum(1/countif(B8:K9,B8:K9))} 在B列,B2=101,B3=010,B4=110,B5=111,B6=000,B7=111,B8=000,B9=101, 条件：B7=B8且都等于0则B9不作显示；B8＝0但B7大于0则B9＝100%；B8大于0则B9=(B7-B8)/B8. EXCEL如何复制公式时让公式行号按+7变化 例如：公式=A1+B1 往下复制的时候变为 公式=A8+B8 =A14+B A=B+B+B+B+B+B+B+B+B+B+B+B+B+B+B A-B×3=C C+2×7+2=1 (2a+b)(a-b)=8 求a,b =SUMPRODUCT(($B$3:$B$8>$B3)/COUNTIF($B$3:$B$8,$B$3:$B$8))+1
