Multiline arguments breaks output

[sn3p]

We're using prettier to format our CSS. This means that lines break when going over 80 characters. It seems that maths.eval breaks lines into an array, and after calling toString on the result the output includes brackets.

For example:

padding: resolve(
      1 + 3)px;
padding: resolve(1
      + 3)px;

Results in:

padding: [4]px;
padding: [1, 3]px;
