Strategy Place Math

Today for Maths Mr Oglvie's groups was told to find 2 question from student in Wakatipu.
I chose Ofa's and Tai's question because they were really interesting but kind of easy to do.
I found find more that 1 strategy for each questions hard.
The question that I found really interesting was Tai's one because in his question he told us to divide in the first line but when you finish reading the whole question in the 3rd line it said to add.
