excel在一个区域中怎样求满足“数字”的求和,例如,一个表格中有0.123,0.234,A.B怎么求数字的和 求公式
1.345*0.345*2.69-1.345*1.345*1.345-1.345*0.345*0.345
1.345 × 0.345× 2.69 -1.345×1.345-1.345×0.345×0.345
2.34x9.9+0.234
计算;1.345^2-0.345x2.69+0.345
0.345²-0.345×2.68+1.345²
0.345²+1.345²-0.345×2.69
2.616+(10.4-0.234/0.65)*0.35
2.34乘9.9+0.234=
