Can anyone help me understand?
I just had a test where we were supposed to calculate the number of possible (implied natural) numbers with 6 digits that add up to 12. I solved it like:
10⁶=x (cause that calculates absolutely all numbers with 6 digits I think)
X-10%=y(because 10% of them have 0 at the start, I think)
Y-53/54 (because the biggest six digit number adds up to 54 and so there's like 53 other addition numbers possible things other than 12)
And that was my final result. I am really bad at math but everyone in my class is and the test was more of a "try and figure it out" rather than "I taught you this formula in class".
The teacher got 90 by his calculations, I can't remember the process,I got 16650, other classmates got other results and I (shamefully) asked chatgpt and got a different answer. Couldn't understand the explication. Was I even close to the right answer or? English isn't my first language and I am not in any way used to using mathematical terms. (I hope I used the right tag)
