Maths Problem

85+52 was a question given to us by Mr Nath, he used some names for the characters and we had to figure it out in our groups….

85+52=??

So we had to figure out how much Miss Smith and Miss Kyee brought together.
So Miss Smith brought 85 water balloons and Miss Kyee brought 52 balloons.
So we added the 10’s first 80 + 50 and it added up to 130 and then we added the 1s 5 + 2= 7 after that we added up our answers and we got 137.

85+52=
80 + 50= 130
5 + 2= 7
130 + 7= 137
