Badi, Adel B. Basic introduction to exponential and logarithmic functions. (English) Zbl 1384.26015 Real Anal. Exch. 40(2014-2015), No. 1, 219-226 (2015). The author presents an introduction to exponential and logarithmic functions, simlar to H. Samelson’s [Am. Math. Mon. 81, 1012–1013 (1974; Zbl 0289.26002)] approach. The use of convexity in the latter study has now been circumvented.
