Find the answer: eight minus six equals the missing number.
When we record an equation in this way, it’s called vertical subtraction. This is because the numbers go down vertically.
To calculate eight minus six, we can use some counters to help us. Here, we have eight counters. And we need to subtract six. That’s one, two, three, four, five, six.
Now we have two counters left. So we can say that eight minus six equals two. We calculated eight minus six using some counters to help us. And we found the answer two.
