Hi as I am a French speaker, and a native English speaker (British). The following phrasing from chapter 3.4 "As a conclusion, we'll make an exercise. Given..." should read "In conclusion, we will complete the following excercise: Given ..." so in French it is normal to use faire (to make), in English for this context complete." Also as a conclusion, is translated in conclusion. If these comments are useful I will continue to provide feedback as I read through the text. Thanks Greg.
