Take away four from 65.
00:00:06.320 --> 00:00:11.630
In this question, we have to subtract a one-digit number from a two-digit number.
00:00:12.740 --> 00:00:16.000
And we have to use the column subtraction method.
00:00:17.650 --> 00:00:26.090
The number we’re taking away from is 65, which has six 10s and five ones.
00:00:27.770 --> 00:00:30.790
And we have to subtract four from this number.
00:00:31.900 --> 00:00:35.770
Four is a one-digit number, so it just has a ones digit.
00:00:37.070 --> 00:00:42.890
So the calculation has already been written for us, which means we can start subtracting.
00:00:44.030 --> 00:00:47.020
And we always subtract the ones first.
00:00:49.010 --> 00:00:55.400
The number 65 has five ones, and we need to subtract four ones.
00:00:56.680 --> 00:00:58.580
This is quite an easy calculation.
00:00:58.890 --> 00:01:03.250
Five take away four equals one.
00:01:04.440 --> 00:01:08.790
Five ones take away four ones leaves us with one.
00:01:10.160 --> 00:01:13.260
Now, all we need to do is subtract in the tens column.
00:01:14.660 --> 00:01:18.440
There are six 10s and nothing to subtract.
00:01:19.330 --> 00:01:23.760
This is because we’re subtracting a one-digit number from a two-digit number.
00:01:24.680 --> 00:01:29.480
Six 10s take away no 10s leaves us with six 10s.
00:01:30.540 --> 00:01:32.370
We didn’t need to do any regrouping.
00:01:32.480 --> 00:01:35.550
We had enough ones to subtract from.
00:01:36.960 --> 00:01:41.570
65 subtract four is 61.
00:01:43.540 --> 00:01:51.750
When we subtract a one-digit number from a two-digit number using column subtraction, first, we have to write out the calculation.
00:01:53.120 --> 00:01:58.820
Then we subtract the ones, making sure to record any regrouping we need to do.
00:01:59.990 --> 00:02:01.900
Then we subtract the tens.
00:02:02.860 --> 00:02:06.370
65 subtract four equals 61.
