I really am that stupid and dumb omg why!

um, i don't wanna sound like a dick or anything, but it's just a maths problem. i don't really see the big deal tbh

 

You're not dumb! The whole reason people ask math questions like that is because people get it wrong all the time.

I don't know if you've already figured out why you get 20, but.. in math, * always goes before + or -, so the first thing you have to do is 10*0, which is 0. Then you add the +s, so 10 + 0 (^see above) + 10 = 20.

 

BODMAS: Brackets, Orders (powers/square roots), Divison, Multiplication, Addition, Subtraction.

Order of operations, my friend.

 

your not stupid mate you have a good head on your shoulders and if am honest I would have said 20.05 :icon_wink

 

Order of Operations:

Please Excuse My Dear Aunt Sally: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.

The 10*0 is figured first, which comes up to 0. Your problem is then 10+0+10, which equals 20.

I was in the same boat as you basically. Terrible at math until one day it just clicked. Part of the difference was that by this certain time, I wanted to know it. I was interested enough in sci-fi to research the real physics of space travel. That involves a fair amount of algebra and a crapton of order of operations problems, so I felt like I needed to learn math in order to better myself.

For me at least, motivation was half the battle. Have a genuine interest in what you're learning and it won't just skip off the top of your brain.

 

BODMAS? Interesting, I was taught PEMDAS, which stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. But yeah, you should get 20. People ask those because its suppose to trick people.

 

trust me , even if i was your age. i still wouldn't get it. i can't do mental math that well. some are good at it , some are not. i wish i was smart like my sister but im not...i may not be smart like her but at least im sweeter haha

 

I used BIDMAS: Brackets, Indecies, Division, Multiplication, Addition, Subtraction. They all amount to the same. You can't have different rules for maths around the world.

 

No, that way you're doing the additions first and then the multiplication. You should do it the other way around.
When it comes to math, just keep calm and think logically. Following the rules will get you quite far.

But you don't have to be good at everything. You may have a different class that you're really good at that others suck at.

 

Math is specifically designed to confuse people and make us angry with its stupid messed up rules

 

I thought it was 10 too!

I honestly suck at maths, and require extra lessons from family, teacher and head of maths at my school. It still doesn't stick, but I always try my hardest.

I'm not going to let a silly maths questions pull me down in life, and neither should you.

 

We learnt BODMAS in Australia. It might be different overseas, but the concept is still the same

 

Same here- I've always been taught PEMDAS. I have no idea how everyone got these different order of operations, but it's actually pretty cool how people come up with ways to remember it

And now that I look at your post it makes a lot of sense, too.

 

math, my dear boy, is nothing more than the lesbian sister of biology - peter griffen.

 

Honestly, I might have said 0, and I'm a math major. All I'd hear would be 3 tens and a times 0 somewhere in there, so my brain could easily put it together as (10+10+10)*0 = 0. Spoken math problems are hard and there's really no point in getting worked up over them.

As for the order of operations, we always learned PEMDAS but we did the MD at the same time and AS at the same time.

 

they're not different rules, it's just a different way of saying the same thing.
