-4 + 6
--------------------
Draw a number line.
Mark a point as zero and mark a point as -4
-----
Put your pencil at zero.
The 1st intruction in your problem is -4 which means "move 4 to the left".
So, move your pencil four to the left of zero.
-------
Your next instruction is "6" which means "move 6 to the right".
So, move your pencil 6 to the right of -4.
---------
You should end up at +2.
--------------------------------
Number line addition requires that you start each problem
at zero and follow the right/left instruction in the order
they are listed.
--------------------------------
Try 2-4-3+5 and see where you end up.
You should end up at 0.
