Question

Five times two is / are ten? My teacher told are, please clarify.​

Answer 1

Answer: Five times ten are ten.

                                                ↓

This is so because we will be considering the product, since the answer is ten which is plural, we are supposed to use are.

Hope it helps!

Answer 2

Answer:

Are  will be the appropriate auxiliary.

Explanation:

The first answer aptly explains this. An additional hint can be taken from the plurality of 'times'.
