00:00:02.990 --> 00:00:08.340
40 plus the missing number plus five equals 49.
00:00:10.140 --> 00:00:19.280
In this question, we need to find the missing number, which when added to 40 plus five equals 49.
00:00:20.820 --> 00:00:24.390
We could use a number line to help us answer this question.
00:00:26.240 --> 00:00:32.500
Our number line begins at 40 and we need to reach number 49.
00:00:33.930 --> 00:00:36.620
First, we need to add five.
00:00:37.150 --> 00:00:53.590
To do this, we need to count forward five places on the number line starting at number 40: one, two, three, four, five.
00:00:54.830 --> 00:00:58.460
40 plus five equals 45.
00:01:00.090 --> 00:01:06.920
The question asks us how much we add to this number 45 to make 49.
00:01:08.080 --> 00:01:12.400
How many places do we need to skip forward on the number line?
00:01:13.780 --> 00:01:20.080
One, two, three, four.
00:01:21.740 --> 00:01:23.770
Now, we can complete the missing number.
00:01:24.130 --> 00:01:28.060
40 plus four plus five equals 49.
00:01:29.800 --> 00:01:35.040
We found the missing number four using a number line to help us count forward.
