My Maths reflection

Math

In math this week that I found out that  there is such thing called a decagon which is  a hexagon with 10 sides also what a hemisphere which is a sphere cut in half. I also learned this :if you swim 15 laps of a 50 meter pool,how many meters did you swim?  A.750

I have also learned this :if it is 4 a.m. now, what will the time be 23 hours later?   A. 3 a.m.

I've learned lots this week (what is above is not all I've learned ) & I hope I learn more next week.
