Dialogue: 0,0:00:00.00,0:00:05.40,Default,,0000,0000,0000,,So we need to figure out what 46 plus 43 is.
Dialogue: 0,0:00:05.40,0:00:06.82,Default,,0000,0000,0000,,Let me write it down again
Dialogue: 0,0:00:06.82,0:00:11.73,Default,,0000,0000,0000,,and I'll write it like this: 46 plus 43.
Dialogue: 0,0:00:11.73,0:00:13.55,Default,,0000,0000,0000,,What we do here is
Dialogue: 0,0:00:13.55,0:00:15.34,Default,,0000,0000,0000,,we just first look at the ones place
Dialogue: 0,0:00:15.34,0:00:17.86,Default,,0000,0000,0000,,We literally have 6 ones plus 3 ones
Dialogue: 0,0:00:17.86,0:00:21.12,Default,,0000,0000,0000,,or you could say 6 and 3, and 6 plus 3 is just 9.
Dialogue: 0,0:00:21.12,0:00:25.22,Default,,0000,0000,0000,,6 plus 3 is 9, so we have 9 ones.
Dialogue: 0,0:00:25.22,0:00:27.00,Default,,0000,0000,0000,,And then you go to the tens place
Dialogue: 0,0:00:27.00,0:00:28.27,Default,,0000,0000,0000,,and there's two ways to think about it.
Dialogue: 0,0:00:28.27,0:00:34.20,Default,,0000,0000,0000,,You could view this as 4 plus 4 is equal to 8
Dialogue: 0,0:00:34.20,0:00:36.24,Default,,0000,0000,0000,,but really, the reality of what we're doing
Dialogue: 0,0:00:36.24,0:00:37.97,Default,,0000,0000,0000,,since we're operating in the tens place
Dialogue: 0,0:00:37.97,0:00:42.07,Default,,0000,0000,0000,,this is really 40 plus 40 is equal to 80.
Dialogue: 0,0:00:42.07,0:00:44.27,Default,,0000,0000,0000,,And we could do the same problem expanded out.
Dialogue: 0,0:00:44.27,0:00:48.56,Default,,0000,0000,0000,,This is the same thing as 40 plus 6.
Dialogue: 0,0:00:48.56,0:00:49.90,Default,,0000,0000,0000,,We've seen this before, right?
Dialogue: 0,0:00:49.90,0:00:51.60,Default,,0000,0000,0000,,That's what 46 is.
Dialogue: 0,0:00:51.60,0:00:58.53,Default,,0000,0000,0000,,And then 43 is the same thing as 40 plus 3.
Dialogue: 0,0:00:58.53,0:00:59.93,Default,,0000,0000,0000,,We've expanded these out before.
Dialogue: 0,0:00:59.93,0:01:01.53,Default,,0000,0000,0000,,And so when you add them
Dialogue: 0,0:01:01.53,0:01:06.33,Default,,0000,0000,0000,,when you add a 6 plus a 3, you get a 9.
Dialogue: 0,0:01:06.33,0:01:11.26,Default,,0000,0000,0000,,When you add a 40 plus a 40, you get an 80.
Dialogue: 0,0:01:11.26,0:01:14.44,Default,,0000,0000,0000,,So you get 80 plus 9, which is 89.
Dialogue: 0,0:01:14.44,0:01:15.80,Default,,0000,0000,0000,,And the whole reason why I did this is
Dialogue: 0,0:01:15.80,0:01:17.20,Default,,0000,0000,0000,,I wanted to show you that
Dialogue: 0,0:01:17.20,0:01:19.83,Default,,0000,0000,0000,,when you're adding 4's in the tens place
Dialogue: 0,0:01:19.83,0:01:21.67,Default,,0000,0000,0000,,you're really adding 40's.
Dialogue: 0,0:01:21.67,0:01:23.60,Default,,0000,0000,0000,,The fact that it's in the tens place represents--
Dialogue: 0,0:01:23.60,0:01:25.87,Default,,0000,0000,0000,,or the fact that the 4 is in the tens place
Dialogue: 0,0:01:25.87,0:01:27.52,Default,,0000,0000,0000,,shows that it represents 40.
Dialogue: 0,0:01:27.52,0:01:29.23,Default,,0000,0000,0000,,The fact that the 8's there
Dialogue: 0,0:01:29.23,0:01:31.90,Default,,0000,0000,0000,,shows that it represents 80.
