In mathematics, when you are presented with multiple operations in one equation, you follow the PEMDAS rule. This rule assigns which operation should be the first priority. The P means parenthesis. So, any expression inside the parenthesis should be calculated first. This is followed by Exponent(E), Multiplication (M), Division (D), Addition (A) and lastly, Subtraction (S). Technically, when all you have left is addition and subtraction, priority doesn't matter because of associative property.
Step 1: Nothing has change. Blake just copied the original equation.
Step 2: Blake changed the placing of the parenthesis. As mentioned earlier, you have to prioritize what's inside the parenthesis first. You can't change the position of the parenthesis. It will matter. Good thing, the answer, in this case, does not matter. But this does not apply to all situations.
Step 3: Blake was correct. He prioritize the <span>(− 9.2 − 0.8) term which is equal to -10.
Step 4: Associative property allows you interchange the order of the operations without changing the final answer. This is applicable to addition and subtraction operations. Hence, this was used correctly.
Step 5: Technically, this was correct because addition is prioritized more than subtraction.
Therefore, Blake's error was in Step 2.</span>

Answer: Transitive Postulate of Inequality (last option)
Explanation:
Let's say we have a vacation where we go from City A, to City B, then to City C. We can use the notation
. If all we cared about was the first and last cities, then we basically say
taking a shortcut so to speak.
This analogy is useful to describe the transitive property.
The equality version is where if we had a = b and b = c, then a = c.
The inequality version is where if we had a < b and b < c, then a < c. In this case, c = 2.
In a sense, its like linking together metal chains. A leads to B which leads to C. So we can just jump from A to C.
It might help to draw out a number line and pick values for a and b like a = 0 and b = 1. That way you can see how a < b, b < c and a < c all tie together.
