okay so if you were to subtract the same quantitity from both sides the inequality still holds

OpenStudy (dan815):

for example| say we have 5>4 which is true if we subtract 2 from both sides 5-2>4-2 we just shifted the numbers down by 2 3>2

OpenStudy (dan815):

same thing with multiplication

OpenStudy (dan815):

suppose a > b then 3a>3b is still true
