^^^no it will be -71. It's like saying you have no money but you have to pay a friend $4 and later on need to pay another friend $67. You are in debt and had to pay $71 all together. Since they are both negative and you're adding...you combine them and get -71.
67 plus 67 plus 67 is equal to 201.

Yes. This only works for multiplication and addition.
3 + 4 + 4 x 15 = 67

An addition equation is the same thing even if the numbers are switched around.

3+6+7+89+4+5+7+9+90+67 = 287

4 plus 8 plus 12 plus 16 is equal to 40.
