# Order of operators

```Hi Jim,

This is about a calculation with potentially hundreds of parameters. I
don't think that parsing the formula to reduce the number of brackets
will be fast enough to make the exercise worthwhile.

I'm building up the formula in a repeat loop, one operator at a time:

1
1*2
1*2+3
etc.

I can leave brackets out when a + or - is added, but I wish I could
leave them all out. I assume a calculation without brackets is faster,
because the symbols between brackets are parsed first.
