00:00:03.330 --> 00:00:05.370
Add 40 to 55.
00:00:06.050 --> 00:00:11.930
Fill in the blank: 40 plus 55 equals the missing number.
00:00:13.210 --> 00:00:17.260
We can use a place value chart to help us add the two numbers.
00:00:18.400 --> 00:00:21.340
We have to add 40 to 55.
00:00:22.550 --> 00:00:24.490
First, we can add the ones.
00:00:25.380 --> 00:00:29.690
55 has five ones and 40 has no ones.
00:00:30.160 --> 00:00:33.170
So five add nothing equals five.
00:00:35.200 --> 00:00:36.750
Now, letâ€™s add the tens.
00:00:37.120 --> 00:00:43.010
Five tens plus four tens equals nine tens.
00:00:43.980 --> 00:00:47.660
40 plus 55 equals 95.
00:00:48.060 --> 00:00:50.590
The missing number is 95.
