That's why it is a good practice to insert blanks to help the eye parse
the sentence without using higher brain functions.
Writing "1.1 -. 1" instead of "1.1-.1" makes it easy to read.

This is a problem based on the perception of the reader.
The expression '1.1-.1' is ambiguous.
Someone who is versed in reading Mathematics, but not as
familiar with J, will parse this as '1.1 - .1' or '1.1 minus 0.1'
for which the expected result would be 1 (resulting from subtraction)
However, someone well conversant with J rhematic rules
will parse this as '1.1 -. 1' or '1.1 less 1'
