        on line 14 of Users/amberjones/Desktop/Sass_Scss_first/sass-project/scss/partials/_functions.scss, in function `col-width`
        from line 15 of Users/amberjones/Desktop/Sass_Scss_first/sass-project/scss/partials/_variables.scss

>>   @return ($page-width - $gap*($columns -1 ) / $columns)```

Answer 1

操作只允许对整数
