## Math Cards

Basic English arithmetic is good practice for junior and senior high school students.  If we aim for math that students learned in elementary school, then the challenging thing is saying the expressions in English.  In particular, large numbers are difficult to say in foreign languages, because it takes a great deal of practice that students rarely get.

Here are three sets of arithmetic flashcards.  The operators used are `+`, `−`, `×`, and `÷`.  The flashcards are A4-size.
