Dumb maths question round 2

[Maximilian]

y = 3(–2)^2 + 12(–2) – 12

= –24

I keep getting 0 though. What am i missing?

y = 36 -24 -12

 

[shortylickens]

Negative 2 squared is 4. Times 3 is 12.
12 minus 24 minus 12 again, is negative 24.

Not hard.

 

[gevorg]

your problem is here: 3(–2)^2 =! 36

 

[Maximilian]

Oh i see. The BODMAS thing where orders come before multiplication is where i went wrong then.

Ta :thumbsup:

Order of operations ... Your homework is geigh

 

[Skunkwourk]

Im completely against anyone asking ATOT to do their homework for them, but you actually tried to solve the problem yourself instead of just asking someone to do the work for you.

That being said, good for you. Im glad you asked for help instead of giving up.

How old are you?

I'm sorry if this sounds harsh, but you seem pretty stupid if you can't figure out how to solve 3(-2)^2. Of course if you are only grade school, I may understand you not getting it.

lol im 25 :$

I hated algebra and maths throughout highschool, never bothered to remember much of it and now as part of my BSc in Computing & IT software development specialization ive to do a small maths module. Ive just kind of tore through it with my hazy highschool knowledge. I enjoy the programming side of things far more

Errr, how can you be a programmer w/o knowing basic things like order of operations? That's not algebra, that's elementary school. Programming and algorithm design involve a fair amount of math. Often it's not anything super high level but you need to have your basics down... even some non-basic things. Like w/o some understanding of limits, if I say quicksort runs in O(nlogn) comparisons, how can you even know what that means?

Guess that's why they put the maths module in this degree

lol, fair enough. I'm honestly surprised you got into CS while hating even elementary algebra. You're the only person I've heard of w/these views.

If you mean computer science its definitely not that, i could never do a CS degree, i wouldn't enjoy it even if i had the head for it. The degree im doing is all about programming, its the open university so i can pick and choose what modules suit me, there's modules for ICT others for solutions development. Im doing all the software development modules and possibly some solutions development with visual basic. Theres the possibility of doing AI as well but im not really game for that, i guy i know who was a maths wiz tried doing AI and dropped out after a year.

Don't feel bad. Some people just don't like math enough to remember any of it, and some people had such terrible teachers that they actually hate it.
