Math's with Mr Vega

Hi today I am going to post about math's.I do math's with Mr Vega every day.But sometimes if he's gone we do it with Miss Mr.For math's today we did it about Adding and Subtracting.MR Vega has to tell us a Question and we have to figure out if its +or -.It was easy in the start but when it got a bit near to the end it got harder and harder.But the problem is that it was hot but there was a lot of sunshine
