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:
Given: X < Y
X ² - Y² < 0
This can be expressed as (X + Y) (X – Y) <0> 0
This scenario, Y is a positive number and X is positive or negative number. This condition proves to be invalid if X = -1 and Y = 1. This is insufficient.
Case 2: X > 0
This condition imposes a pre-condition of both X and Y are positive numbers and X is less than Y. For example: X = 2 Y = 3 ect. This is sufficient to prove that both (X + Y) (X – Y) < 0
