Take away nothing and you still have what you started with. 7 − 0 = 7.
Step 1: Let's Learn
Read it, or press Listen and follow the words.
Take away all of them and none are left. 7 − 7 = 0.
Take away nearly all and just one is left. 7 − 6 = 1.
Taking nothing changes nothing
7 − 0 = 7 because you removed nothing. It looks too easy to be a real question, and it is still a real question.
Taking everything leaves zero
7 − 7 = 0. Zero is the answer, not a way of saying there is no answer.
Step 2: Try It Yourself
Tap and try it out.
7 take away 0 makes 7.
Step 3: Watch an Example
One step at a time.
