Input:
expand(tosum(exp(x)))

Write:
`expand(tosum(exp(x)))`



Compute: $$expand :\\ \ \sum _{k=0}^\infty \frac {{x}^{k}}{(k)!}$$

Output: $$ expand :\\ \ \sum _{k=0}^\infty \frac {{x}^{k}}{(k)!} == 1+x+\frac{1}{2}\ {x}^{2}+\frac{1}{6}\ {x}^{3}+\frac{1}{24}\ {x}^{4}+\frac{1}{120}\ {x}^{5} $$ Result: $$1+x+\frac{1}{2}\ {x}^{2}+\frac{1}{6}\ {x}^{3}+\frac{1}{24}\ {x}^{4}+\frac{1}{120}\ {x}^{5}$$
