Math Is Fun Forum

Well, one of the reasons I find her attractive was because in my country it's rare to see a big and black woman who is cute.

312=0+1-2+3*4*5*6-7*8+9

Is that sarcasm?

(8-5)(0+1+2+3+4)+9-(7-6)=308

I tried to say "happy pi day" to my former crush via Facebook chat and she kept answering with uploading memes.

Me: "Happy π day..."
Her: ("one does not simply" meme) "One does not simply remember pi day"
Me: "I do 8| "
Her: (lame joke eel meme) "Why do people get excited about pi day? Who knows, it's completely irrational"
Me: "But... Golden Ratio is also irrational... "
Her: (Stoner Stanley meme) "If today was really 'pi' day, it would never end"
Me: "Toilet humor?"
Her: ("Meh" hand Facebook sticker)
Her: (peeking cat) "Don't mind me. please, do continue..."
Me: "Sorry, I am going to π..."
Her: (grumpy cat meme) "Yikes. I almost smiled."
Me: "That suits you well... -_- "
Her: (Vladimir Putin) "Thanks for Putin up with me"
Me: "........"
Her: (Jackie Chan rageface)
Me: "With this I show a white cloth as a sign of surrender"
Her: (troll rageface) "You mad, bro?"
Her: (bald man whose face looks like Tintin pointing at me) "Guess who can't keep up"
Me: "Sis Cal......!!!!!! >.< " (that's my adorable name for her)
Her: (math Wonka meme) "Problem is, I lose interest... very quickly"
Me: "Yeah yeah... I know that..."
Her: (someone with a hat and glasses shouting) "Am I right? Or am I right?"
Me: "OR"
Her: (grumpy cat meme) "Hahaha. No."
Me: "Grumpy cat represents you really well."
Her: (NO rageface) "NO"
Me: "Yes. Someone cute who is hard.to.smile."
Her: ("no bear" meme) "How about no"
Me: "And a bear suits you the most."
Her: (someone shouting) "Don't call me fat! I already know I'm fat!"
Me: "Not just that, but that bear is big, black, yet strong and cute... Just like you..."
Her: (Dwayne meme) "False"
Her: (Someone bald and black holding a mic and shows a palm) "No. I'm not good enough"
Me: "Which parts are false? I mentioned 4 factors there... "
Her: (grumpy cat meme) "I am not cute. Stop thinking I'm a feet teddy bear."
Her: ("I don't always" meme) "I don't always try to understand women. But when I do, it terrifies and confuses me"
Me: "Nah, you are a cute girl..."
Her: (a girl who seems giving up conversations) "Yeah, sure. If you say so."

Me, neither.

1. Let A(t) = 3- 2t^2 + 4^t. Find A(2) - A(1).
A(2) - A(1) = (3- 2(2)^2 + 4^2) - (3- 2(1)^2 + 4^1)
Sure you can continue.

How can we input it to the abacus?

Thank you. Now I am looking about how to operate fractions on abacus for the last chapter.
