Again, subjectively, I remember being in grade 8, and if math didn't come to you, it was considered fine, and teachers would excuse your lack of comfort as (paraphrased): “Math is difficult”. Just like today, and it seems like the math got easier because we were doing stats and variable-based algebra, where today in grade 8, they're doing fractions, and not proper fraction, they don't reduce them.
One of my old classmates from primary school works at a dinner in my home town, she was never good at math. The other week she gave me a bill, and I placed $30 on the table, and she could not tell me how much change she owed! I think it was $9.48, and I didn't want change, but she struggled to compute the number, why? I understand we all have calculators, but you should be able to check simple work in your head, otherwise, how are you sure to any degree if you're right or wrong?
I've seen this kind of problem with other engineers, where they can't grasp the calculations, so they'll get confused if a number should be 4, 5 or 15. In most cases, you should be able to figure out a ballpark, and then once you're reasonably sure, use a calculator, and if your number matches, it's all good, and It's way off, you have an issue. I've seen engineers who are literally 1000x off their assumed value, and not some complex Nth dimensional radio transmission calculation, a ballpark “will it work” number. One Jr Engineer calculated a value of 2 (or something like that), when some a basic look and numble it was 11 000, he was truly, and completely, lost on how that worked.
This goes back to asking the teachers questions, how do you get X, I can see step 1, 2, and 3, then something happens, and now we're on a step 5, where is step 4, and how do you get that value? I've had a teacher laugh at me and tell me it's safe to assume... no it's not. When I showed my younger daughter how to do the calculation in the "traditional" manner, she got it almost instantly, and she could never explain the "new" method, but her teacher couldn't either, and for the matter, neither could the text book.
