14.9-10.1 They wanted me to choose the best estimate. What does estimate means?

they arived at the answer 5.

Estimate means to take an educated guess at the answer. In this problem, 14.9 is almost 15. 10.1 is about 10.

15 - 10 = 5.

Oh thanks. I understand this one.

You're welcome. :-)

You're welcome! I'm glad I could help you understand. Remember, when you're asked to estimate, try to round the numbers to make them easier to work with, and then perform the necessary calculations. If you have any more questions, feel free to ask!
