Nine take away three equals what?
In this question, we start with nine. And then, this symbol means that we need to take away the next number. What is left if we start with nine and we take away three? One way we could find the answer is to use counters. We can start with nine counters and then take away three of them: one, two, three. How many counters are left? There are six counters left. Nine take away three equals six.
Another way we could find the answer is to count back in our heads. We can imagine a number line. And we can start with the number nine. Taking away is the same as counting backwards. So we can count backwards three places: one, two, three. If we start on the number nine and we count back three, we reach the number six: nine, eight, seven, six.
Nine take away three equals six.
