Complete the subtraction
sentence. Six take away what equals
zero.

As part of this question, we’re
given a subtraction number sentence. But it’s got a missing number
in it. Six take away what equal
zero. To help us understand what the
question is asking, we’ve also got a picture. And if we count them, we can
see that the picture shows six sweets. But each of the sweets has been
crossed through; it’s been taken away. And there aren’t any sweets
left. Let’s try modeling this using
cubes. Here’s a line of six cubes to
begin with. Now, how many do we need to
subtract so that we’re left with zero or none?

We’ll take away one, two,
three, four, five, six. We’ve taken away all of
them. Six take away six equals
zero. If we start with a number, we
take away something, and we’re left with nothing, the number that we’ve taken
away must be all of the number we started with. So in this number sentence, the
missing number is six. Six subtract six leaves us with
zero.
