Question

What is the estimated song of 231 + 529 ​

Answer 1

760.

Explanation:

31 + 29 = 60

2+5 = 7.

Answer 2

760 because you add 200 and 500 then 31 and 29 are both very similar to 30 so you add both of those together and then add that to 700. Tell me if this doesn’t make sense! I will try and explain better
