I have been asked in the comments numerous times, why step three just calculates left to right?

“Shouldn’t you do addition first?”.

So I am adding this explanation section to the top of the article (it is similar to information in the linked related posts).

 

 

Order of operations (excluding the first two parts of Parenthesis/Brackets and Exponents/Orders/Indices) is [DM] or [MD] followed by [AS] or [SA].

So, Multiplication and Division can be done at the same time and then Addition and Subtraction can be done at the same time.

 

 

The correct answer is as follows:

 

Question: 3 – 3 x 6 + 2

 

Multiplication first: 3 – 18 + 2

Left to right: -15 + 2 (or Addition first: 3 – 16)

Answer: -13
