How do I know whether to round all the numbers first, THEN estimate, or to find my answer THEN round? I was doing a favor for my teacher, and I missed that part. She went pretty fast throught the lesson, so I forgot to ask her. Thank you!

You're supposed to round the numbers first and estimate.

For instance, 58 + 63 rounds to 60 + 60 = 120
