Hi, i would like to ask you for some help about how to add these exponential logs...

If A = 200e^-0.2m

and B = 10.5e^0.3m

what is A + B

seriously, i cant add them... and what i mean is adding the 2 equations... and by the way i dont know how you guys can make the powers shown here so i just typed '^'... sorry...
