Description

When evaluating with multiple expressions and one of them has an error:

math.evaluate(["1+1","2+"])

The error is:

SyntaxError: Unexpected end of expression (char 3)

I would like to know which is the expression with the error: SyntaxError: Unexpected end of expression (expr 2, char 3)

Contributor guide

Research direction
Locate the evaluate function in the mathjs source code, find where parse errors are thrown, and modify the error message to include the index of the expression in the array.
