How to learn how to solve equations in Julia 1.0? Because I am a beginner, I am only interested in relatively simple problems such as basic optimization. I found a book that seemed relevant but it predates Julia 1.0: Julia Programming for Operations Research: A Primer on Computing.

For example, I have the equation:

1/((1+p)^30)*10,000=100

I need to solve p. How to do it in Julia 1.0?

The example was recently discussed on Statalist. In addition to a partial programming solution in Stata, one user suggested to simply type the input online into Wolfram Alpha which works as a simple non-Julia solution. I considered the Julia packages JuMP.jl, Optim.jl and IterativeSolvers.jl but none seem ready for 1.0. My only attempt in Julia was to simply type the input but then I get this error:

```
julia> 1/((1+p)^30)*10,000=100
ERROR: syntax: "(1 / ((1 + p) ^ 30))" is not a valid function argument name
```

I looked at the Julia manual for functions but could not find a relevant usage example.
