My T158 is playing someone else’s tune, not mine. I grabbed my CASIO FX 7000 G manual and attempted to input their canned Simpson’s rule program. The Casio then insulted me with a collection of GO and SUN errors. I am going to take a walk with my beagle and maybe fashion an abacus from sticks and dried wild cucumbers.
