Ms. Halsall has made a mistake when calculating order of operations. What is the mistake? You should answer in a full sentence. 
Mistake at Step 2. Ms. Halsall should not have added 4 and 8, and instead should have multiplied 8 and 3 because multiplication comes before addition and subtraction.

Mr. Shapiro and Ms. Halsall are arguing about absolute value. Ms. Halsall says the absolute value of 4 is -4. Mr. Shapiro thinks she's wrong, but is not sure of how to explain why. What is Ms. Halsall's error?
Ms. Boyce is incorrectly thinking that the absolute value of a positive number is negative. Absolute value must always be positive or zero because it describes a number's distance from zero.

A new point Z is added to the left of point B. Which is greater:
z * d or z * g
z * d
because since we know that z is negative and d is ALSO negative, we will be left with a positive value.
z * g
will leave us with a negative value, and positive values are always greater than negative values.

Minnie wrote the following on her paper. What is her mistake? What should her paper look like?
2^3 = 6
Minnie incorrectly multiplied the exponent by the base, instead of repeatedly multiplying 2 three times.
2*2*2 = 8

Which has a greater value?
-52 or (-5)2
(-5)2 = -5 x -5 = +25
-52 = -5 x 5 = -25
+25 > -25, thus -52 < (-5)2
