# Thread: how do you calculate?

(i see a 10-5 or 8-3 in the 32 to 37 step, my mind sort of groups known additions without thinking)

I was thinking I do a lot of going in order like that. Like 2539+3686, I'd go 5 11 61 11 621 15 6225. I don't really follow any set methods, just be aware of the underlying principles and use whatever intuitively feels best for the problem.
Yeah same. I also don't think numbers in words, I just see them in my mind as a visual of the "number".

3. ((5-3+(6x5)) + (8+2-5)) x 2
I got confused as thought you added no brackets around the numbers making it like this:
(5-3+(6x5)) + (8+2-5) x 2
Therefore I ended with a different answer until of course I looked at the equation again. Brackets are an enemy.

4. If you'ld write it as a real equation the brackets can be dissolved completly:

(5-3+6*5+8+2-5)*2

5. look at math problem... vaguely attempt solving math problem until I realize that it's boring because I don't even know WHY I'm solving it (I beleive in story problems and story problems only)... conclude "fuck it!" and check out someone else's answer

i say this in my head: five two sixty thirty two, then keep 32 in mind by remembering 3 and the number before that. then eight ten five = five. thirtyseven sixty seventy two two = 4 = 74

how do you calculate this or can you explain it?
2 X 37 = 1 + (T 37)

Before I read anything else this is how I do it:

six times five is 30 plus 5-3 so plus 2 = 32. plus 8 + 2 which is 10 minus 5 which is 5. So 32 + 5 = 37. times 2 is .. 35 + 35 = 70 + 4 = 74.

I'd use BODMAS.....

Boackets Off
Divide
Multiply
Subtract

Enjoy

9. I look at the equation and then my mind goes like this:

Then I get the calculator out.

10. In the U.S., it's PEMDAS.
