I can't remember(nor do i want to) how to add/subtract fractions and mixed numbers. One of you nice kids work these out for some old school rep. Thanks. (-4/5) - 7/8 = (-1/3) + 3/8 = 1/3 - (-5/3) = 9/5 + (-4/3) = (-10/7) + 1/6 = Show your work... :chuckles:

Have to find the Least Common Denominator: (-4/5) - 7/8 turns into (-32/40) - 35/40 = -67/40 = -1 27/40 (-1/3) + 3/8 turns into (-8/24) + 9/24 = 1/24 1/3 - (-5/3) = 1/3 + 5/3 = 6/3 = 2 9/5 + (-4/3) turns into 27/15 + (-20/15) = 7/15 (-10/7) + 1/6 turns into (-60/42) + 7/42 = - 53/42 = -1 11/42

Rather simple once you get the hang of it to do it in your head. (-1/3) + 3/8 = x common denomenator between 3 and 8 is 24 -1 x 8 = ? (you're multiplying the other base in 3/8 (the #8) by the top # in -1/3 (I forget the name of that). 3 x 3 = ? -8/24 + 9/24 = x x = 1/24

The good news is Big Max has the money to pay for a tutor when little max starts calculus. You know Big Max is a job creator. :chuckles:

He stayed home sick. Doesn't have math book for me to re-teach myself. Math sheets due tomorrow...last day before break. :chuckles: You guys are the best!!!! Thanks!

By the looks of your math memory and what your son is learning, you are about 2 or 3 years away from not having a prayer to reteach yourself, ie your son is on his own or needs a tutor. Math is my thing, so this was easy, but my third grade daughter was shocked when she figured out she is already a better speller than I am.

I love this forum. I've spent time on a variety of different forums in the past, but this one has by far the best mix of information, sense of community, designated curmudgeons, and lulz.

I just realized there is a definite visual component to math, more-so than before. - Rather, maybe, the visual component is more of a help to some than others. I loved math until it started getting too complex for me (around college) and I become disinterested in it. This thread has also made me realize that I'm able to remember things I thought I'd never use in my life lol.

that doesn't show him how to do it. Max, I hope you showed him how to do it and let him calculate the actual answers.

For what you did to this forum. I hope your son fails.... Tell Minimus if he needs some math help and a new pot connect hit up Uncle Bill.
