Parse these numbers a little bit for us.

为我们解析一下这些数字。

Since there is a maximum of 16 rows, we store the row address in a 4 bit number.

由于最多有 16 行，我们将行地址存储在一个 4 位数字中。

You feed it a 4 bit number, and it connects the input line to a corresponding output line.

你给它一个 4 位数，它将输入线连接到相应的输出线。

So if we want to avoid overflows, we can extend our circuit with more full adders, allowing us to add 16 or 32 bit numbers.

所以如果我们想避免溢出，我们可以用更多的全加器扩展我们的电路，允许我们添加 16 或 32 位数字。

We've run the numbers and found that less than two percent of you support Radiolab, and if we could get that number up just a hair, just a little bit, it would make a huge difference.

LULU：我们统计了这些数字，发现只有不到百分之二的人支持 Radiolab，如果我们能把这个数字提高一点点，一点点，就会产生巨大的变化。
