00:00:01.760 --> 00:00:06.840
29 plus 931 equals what?
00:00:08.360 --> 00:00:15.960
To solve this problem, I’m going to take the larger of the two numbers and line it up with a decimal place to the right.
00:00:16.800 --> 00:00:25.480
I’ll add the 29 just below it, being careful to make sure that where the decimal point is is lined up.
00:00:26.840 --> 00:00:39.000
Once we’ve lined up our 931 and 29 correctly, we can start to add by place value.
00:00:40.040 --> 00:00:49.600
We can add the one and the nine in the ones place: one plus nine equals 10, 10 ones.
00:00:50.760 --> 00:00:58.040
We need to carry our one over to the next column and leave a zero in the ones place.
00:00:59.240 --> 00:01:08.080
So we carry our one over to the top of the tens place, bring down our decimal point just to make sure we remember where it is.
00:01:09.520 --> 00:01:17.760
Now in our tens place, we’re going to add one plus three plus two, which equal six.
00:01:18.920 --> 00:01:29.120
In the hundreds place, we have a nine and nothing underneath it; we could say nine plus zero equals nine.
00:01:30.440 --> 00:01:39.920
When you add 29 and 931, your solution is 960.
