Addition math
I enjoyed doing 120-degree angle the most because it is challenging to me. The hardest construction is rectangle because construct the rectangle have so many processes to do. My favourite way to remember is to know the use of compass such as where an arc meets an arc it is the half.

Addition math

I think that percent is a bit easy because every number included to 100 even though it is easy but it is useful in our own life. Decimal is a bit harder than percent because it can be every number. It makes me think and participate in it. And I think that word problem is the hardest than everything because we need to read what is the question ask. We need to understand the question so we can do it. These are all of my thought about percents, decimals, and word problems.
