You are probably the biggest reason why I'm confident of getting a high predicted grade!

[@OSC1990]

Thank you so much! Although it's your hard work and willingness to learn that is likely the reason. Keep up the hard work! Cheers, Mitch

Hey, Love your video and not to be that guy but at 3:05, you made a mistake I think. 2(-5) = 10 not -10. Anyways love your video. Thanks for doing this

[@OSC1990]

Hi, and thank you for reaching out. I took a look, and in the video at 3:05, you are correct that I am calculating 2 x (-5). However, when you multiply a positive by a negative, that always gives a negative, so my answer of -10 is correct. Good luck with your studies, I hope you're enjoying the IB :)

@@OSC1990 damn, forgot that rule. Thanks

@@OSC1990 I was thinking instead of 2*-5 as -5 *-5. I guess this is what I get for studying late for a test
