I actually found the slideshow very helpful for journalistic math. It was a nice refresher to understanding percentage change, rate per thousands, Mean and medium. As a journalist you need to make sure that all your math information is correct because if it isn’t your actually not being truthful. I know math can be hard at times but if you use different resources you can understand math again. I also liked how the slideshow actually showed at the end how to write number in AP Style. I found that very helpful because I wasn’t sure exactly how to write out different number in AP Style before.
