Which term means the operation of doubling a number?

Explanation:
Doubling a number means getting two times as much as the original value. In math, we describe that as twice the number, or two times the number. So the term that matches doubling is twice (often spoken as “two times”). For example, doubling 7 gives 14, which is twice 7. The other words describe different operations: plus is addition, halves means dividing by two, and minus is subtraction.
