点 point

My fortune teller says that by staring into TEN flames, she can see any point in the future.

a) a dot like the decimal point. . . .actually the 4 dots at the bottom of this kanji are referred to as tens.

b) a point of conversation, as in "That's not the point and you know it!" LAZY

the important points ★★☆☆☆
要 (important) + 点 (point) = 要点 (the important points)

the important points (unlike the related word 重点（じゅうてん）、　要点 is more than one point - more like a summary. Like instead of writing an essay, you'd just do a series of bullet points.
Example phrase:要点だけ話して！　("Get to the point!")
