Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
A) X cannot be = y then the whole equation will not be zero (False)
B) if X = 5 then (X-5) is zero then whole equation is zero no matter what Y is (False)
C) if Y = -2 then no matter what X is the whole equation is zero for exmple X = 1 where 1 > -2 (False)
D) Again is X = 5 and Y is anything toher than -2 still the equation holds good but XY != -10 (False)
