Math: Trying to Help My Daughter w/ PSATs

[Redz]

negative 5 minus negative 4 = -9

a negative x a negative =  positive

so -5 x -9 = 45

the "double negative" doesn't apply to subtraction like it does multiplication or division

Sorry, this my friend is not correct. negative 5 minus negative four with always equal negative one. There is a typo in the exam, unfortunately this happens a decent amount of the time.

yup

I stand corrected.  Boo me.

If it's any excuse I had a headache at the time.  

still do, come to think of it

Hey -- no shame in making a math error.  Math makes my head hurt.

and I passed the Math portion of the General Curriculum teacher's exams on the first try!

This was a brain fart/memory mistake.

Anyhow

GO C's!
