9th Algebra
Im in 9th grade algebra. and we are learning adding and subtracting real numbers. im stumped on a couple of problems. I get confused when i see the absolute value lines. Does that change the munber? Do i just go on with the problem as if they werent there?
And i have NO idea how to do 2/5  7/8?!?

2/5  7/8
= 2*8/5*8  7*5/8*5
= 16/40  35/40
= 19/40posted by oneirocritic
