Comment on I dunno
AquaTofana@lemmy.world 1 week agoI fucking suck at math and totally just re-proved it to myself with this problem lmao.
It didn’t make sense to me to multiply the 3 & the 5 with zero consideration for the “2”. I have ALWAYS struggled with the steps to solve these types of equations.
So the answer I got was 21. Some of us are just bad with numbers, I s’pose.
This is absolutely not a problem of being bad with numbers. That’s like if I had trouble reading a Chinese sentence about gardening and said I’m just bad with plants. My issue is that I’m not familiar with the notation used to explain the concept - not a problem with the concept itself that the notation merely arbitrarily symbolizes.
Being good or bad at math is not really an inherent thing, aside from some geniuses and some people with disabilities. If you want to be good at math, you can be!
If you don’t remember pemdas, you can use the longer P.lease E.xcuse M.y D.ear A.unt S.ally.
Its order of operations, to get rid of brackets do the internal, then the 5 tells you there was 5 sets of the amount in brackets. Rather than 2+5 first.
That’s the answer I arrived at as well, don’t feel so bad. I’m more of a writer than a calculator, though.

The numbers in the equation and their totals are completely irrelevant to the order you perform the operations.
I don’t think it’s an issue of “being bad with numbers”, I think the issue is not understanding the logic or being able to understand the bottom up type of thinking or something.
