00:00:02.820 --> 00:00:07.800
Find the answer: eight minus six equals the missing number.
00:00:08.980 --> 00:00:14.480
When we record an equation in this way, it’s called vertical subtraction.
00:00:15.170 --> 00:00:18.730
This is because the numbers go down vertically.
00:00:19.620 --> 00:00:24.290
To calculate eight minus six, we can use some counters to help us.
00:00:25.510 --> 00:00:27.750
Here, we have eight counters.
00:00:28.480 --> 00:00:30.970
And we need to subtract six.
00:00:31.610 --> 00:00:39.780
That’s one, two, three, four, five, six.
00:00:40.550 --> 00:00:42.630
Now we have two counters left.
00:00:43.410 --> 00:00:47.180
So we can say that eight minus six equals two.
00:00:48.440 --> 00:00:53.660
We calculated eight minus six using some counters to help us.
00:00:53.880 --> 00:00:56.220
And we found the answer two.
