I’m honestly terrible at mental math — especially when it comes to adding and subtracting negatives and positives. It’s kind of funny because I do really well in adv math classes, but I've been way too reliant on a calculator. Does anyone have any websites or resources they’d recommend for practicing?

To improve your mental math skills, especially with adding and subtracting negatives and positives, here are some actionable resources and tips based on the most helpful WSO content:
MathHeads.net: This is a gamified platform designed to enhance mental math and analytical skills. It offers three difficulty levels (easy, medium, and hard) and is available on both desktop and mobile. Practicing on MathHeads for just a week can significantly boost your confidence and speed.
TraderTest.org: This site is specifically recommended for practicing speed math tests. Start with the easy section and aim for 15 reps daily. It’s a great way to simulate the pressure of timed tests and improve your accuracy.
Daily Practice Routine: Dedicate 30-40 minutes daily to mental math exercises. Track your progress by writing down your scores and observing your improvement over time. This method helps build intuition and confidence.
Mental Math Tricks: A simple trick shared in WSO threads is to round numbers for easier calculations. For example, instead of adding 17, add 20 and subtract 3. This approach simplifies calculations and reduces errors.
By consistently practicing with these tools and techniques, you’ll see noticeable improvements in your mental math abilities.
