In mathematics, the term double means to multiply by 2. For example, if you have the number 5 and you double it, you get 10. This is because 5 multiplied by 2 equals 10.
On the other hand, squared means to multiply a number by itself. For example, if you square the number 5, you get 25. This is because 5 multiplied by 5 equals 25.
So, to summarize:
- Double means times 2.
- Squared means times itself.
Understanding these terms correctly is important in solving mathematical problems accurately.
