Hey guy is there a possible way to calculate e^x without calculator

I tried to do so using Taylor Series " 1 + x + (x^2)/2! + (x^3)/3! + (x^3)/3! + (x^3)/3! + ...

I tried to calculate series up to 30 terms but it works for 1 but as I try 2, 3, 4 ..... the precision keeps on loosing

What am I doing wrong??????????????
