Gold 🥇 100%
Silver 🥈 Greater than 90%
Bronze 🥉 Greater than 80%

Purpose: To recognize the importance of mental math, and to help anyone who wants to improve for free. My easy setting includes numbers between 0 and 5, my medium setting includes numbers between 1 and 12, and my hard setting includes numbers between -15 and 15. Note: If you choose the Easy or Medium setting on Subtraction, my program will choose the larger number first to avoid negative integers. However if you choose the hard setting, then you are expected to know how to handle numbers less than zero. Enjoy!

Acceptable scores are anything greater than or equal to 80%.

Nearly Acceptable scores are anything greater than or equal to 60%.

Anything less than that indicates that you need more practice.
