I tried my best in writing this, to understand it the easy way.

All is quite logical here. Three observations here.

1. There are operators that only exist in math are (*, /, -). They try to convert literal into number and calculate. If it's not possible, than NaN
2. Whether '+' is concat or math operator depends on the type of left argument.
3. There's a curious case of null converted to 0, but undefined converted to NaN, also ' \t \n' converted to 0

1, Yes correct
2, + can do 2 things, concat or addition.
addition if both operands are numbers
concat if one of them is a string

This clears out any confusion:

3, Math conversion rules gives more clarity

Happy learning.
