Hello,

I’ve started looking through this course as Stephen from the C++ beginners course has started looking into vectors, and understandably he didn’t go into detail as that’s not the point of the course. So I reattempted the Math course (accessed twice before and stopped in the Algebra & Equations section’s first quiz). I decided to go through it until the Vector’s section as even when I went through Stephen’s course on C++ some details he went over I wasn’t following mathematically on calculating movement/gravity, etc.

I seem to be struggling with Gary’s detailed information on flipping parts of the equation to find the missing value/variable. e.g. `10 => -2x + 5`

Is there a methodology in maths where you can flip parts of the equation I’m not familiar with? I didn’t understand why moving ‘+5’ became `-5 + 10 => -2x`

. Same goes for moments later where the equation becomes `5/-2 <= x`

. Also noticed the sign for -2 doesn’t become inverted unlike the + 5 from the first equation.

So far I feel it’s going over my head. Although the first section is useful as a lot of segments I was either weak at before or had limited knowledge, even if still abstract in it’s utility for me currently. However it seems some concepts being discussed are at a skill level I’m not grasping or I’m missing key points that allow me to follow along.

Should I be expecting this to make sense this early in the course or does it come into play later?

Thank you in advance for helping and thanks for reading.
