What is nine take away
zero?
We know that the number zero
stands for nothing. But what happens when we take
away nothing from another number? This question asks us, what
happens when we take away zero or nothing from nine? Let’s model this number
sentence. Perhaps we could use a ten
frame.
Now, the first number in our
subtraction is nine. So let’s represent this by
putting nine counters on our ten frame. Now, we don’t need to count
these out. Nine is only one less than
10. So we need to almost fill our
ten frame, just leave one space. Here are our nine counters. And in our subtraction, we’re
told to subtract or take away zero. So let’s pick up the number of
counters that we’re told to subtract.
Here we go. Watch the counters. Done. Of course, if we take away
zero, we’ve taken away nothing. We didn’t need to pick up any
counters at all. When we subtract zero from a
number, that number will stay the same. And so if we subtract zero from
nine, the answer is going to be the same as the number we started with. The answer’s nine. Nine take away zero leaves us
with all of the amount we started with. The answer is nine.
