I think it may be this :     ask for x     if x< 0 :         return −x     else :        return x    I also think it would be like that on python :  x = float(input(′′value of x ?′′))  if (x<0) :      print ((−1)∗x)  else :      print(x)

$$\mathrm{I}\:\mathrm{think}\:\mathrm{it}\:\mathrm{may}\:\mathrm{be}\:\mathrm{this}\:: \\ $$ $$\:\:\:\mathrm{ask}\:\mathrm{for}\:\mathrm{x} \\ $$ $$\:\:\:\mathrm{if}\:\mathrm{x}<\:\mathrm{0}\:: \\ $$ $$\:\:\:\:\:\:\:\mathrm{return}\:−\mathrm{x} \\ $$ $$\:\:\:\mathrm{else}\:: \\ $$ $$\:\:\:\:\:\:\mathrm{return}\:\mathrm{x} \\ $$ $$ \\ $$ $$\mathrm{I}\:\mathrm{also}\:\mathrm{think}\:\mathrm{it}\:\mathrm{would}\:\mathrm{be}\:\mathrm{like}\:\mathrm{that}\:\mathrm{on}\:\mathrm{python}\:: \\ $$ $$\mathrm{x}\:=\:\mathrm{float}\left(\mathrm{input}\left(''\mathrm{value}\:\mathrm{of}\:\mathrm{x}\:?''\right)\right) \\ $$ $$\mathrm{if}\:\left(\mathrm{x}<\mathrm{0}\right)\:: \\ $$ $$\:\:\:\:\mathrm{print}\:\left(\left(−\mathrm{1}\right)\ast\mathrm{x}\right) \\ $$ $$\mathrm{else}\:: \\ $$ $$\:\:\:\:\mathrm{print}\left(\mathrm{x}\right) \\ $$
