Really Nasty MathCounts Problem

N 2 hours ago by OronSH
2019 MathCounts National Sprint #29

How many of the first $100,000$ positive integers have no single-digit prime factors?


Side note: Just HOW are they supposed to solve this in like 5 minutes?

Hi guys,

I realized I suck at math after mocking recent state sprint problems. I keep getting ~23, even though 1-2 weeks ago I was capable of mocking 28s on old nats problems as well as a 27 on last year's state. I am always able to finish 28-29 problems but am not capable of avoiding silly mistakes.

for example, on 2017 p10 i flipped the fraction, on 2017 p12 i wrote the numbers incorrectly in the process of arithmetic, on 2017 p14 i assumed there was symmetry, on 2017 p16 i forgot to square, on 2017 p15 i skipped over a number while bashing, on 2017 p30 i forgot a case.

I am suddenly making lots of sillies on trivial state problems (1-2 weeks ago i rarely made any mistakes), any tips on how to avoid them? it's especially cooked since
1. im in WA
2. i need nats
3. state is rumored to be easy
4. state is rumored to be sillyable
5. WA cutoffs are gonna be 42+ this year

thank you

Competition Day Mindset

N 3 hours ago by jkim0656
Hi! I'm taking the MATHCOUNTS State test on March 15. I know that there's probably not enough time left for significant skill improvement, so I wanted to ask about things I can do on competition day to help me be at my best. Most importantly, I'm curious about what mindset I should have during the test. Should I be confident and cocky, or more humble and negative? I'm just curious about what preparations prior to the test help the most. Thanks!

I should learn from your accuracy. :omighty:
meanwhile I had 10 minutes left in the end to check my work, and I still sillied a bunch of easy questions.

I got a 20, this was slightly lower than I had expected. I was expecting either 21-22 based on answer keys, as I was unsure of how I answered one question. However, I guess I got that one wrong, and misbubbled another. I’m happy I at least got hr, and I have one more year to shoot for perfect.
