Well, I thought you might say that but I'd say the same thing about the GED. If you accept that a high school education should include mathematical skill through basic algebra, and if you accept that the GED should prove one has the equivalent of a high school education...

Indeed, I looked up the official site and have found that the GED's mathematics component includes the following:

"Number operations and number sense; measurement and geometry; data analysis, probability, and statistics; algebra, functions, and patterns."
