I do not understand the computer analysis of this game

I played a great game, made many blunders but still managed at a specific point in the game to find the winning strategy.
On the 46th move right when the rook took the pawn is when I found the winning strat, but here's what's bugging me, those numbers the computer shows for every move says moving the bishop first was a mistake, it suggests moving the queen first. Really that beats me, then i see it awards +13 for moving the rook there when really it's a bad move -
And quite a few other moves before while I did make blunders, the computer has a brain I can't really follow -

Like turn 10 too, where it says I should have went d3 with the bishop instead of e2, blocking my queen that way seems like a huge mistake which is the only reason why I paid attention not to do so

I was really hoping someone could help me understand what was wrong / could've been better and maybe explain why. Blunders are blunders but some moves I did think through were considered not optimal and I wonder why :l

Thanks if anyone feels like helping me with this

So specifically which moves you didn't understand?
You have to take into account that the computer thinks many moves in advance so sometimes suggestions are just positional.
If you don't understand why the computer says it's a good move, try to follow it and see where it leads.

10 Be2 fails to 10..cxd4 and 11...Bb4+, so Bd3 is better, but white was lost anyway.
24 Bc4 fails to 24...Rd8 and black defends everything, while 24 Qe8+ delivers checkmate

Like tpr said...
24. Qe8+, Kg7 25. Qf8+ is a mate in 2 that you missed

Black can bring his rook back to the backrank to prevent checkmate if you attack it first with the bishop
24. Bb4, Rd8 25. Ba6, Kd7 26. Bxd8, Rxd8

Sorry I'm not sure of the best way to share moves so I'll do it individually, like here

so I guess sometimes it makes sense to play it out, and now that I go back the lil numbers make a bit more sense, instead of + or - something it only says #20 so I guess I simply mainly don't get the system

'10 Be2 fails to 10..cxd4 and 11...Bb4+, so Bd3 is better, but white was lost anyway.'
I try to make sense of this but I just can't :(

Again:
10 Be2 cxd4 11 Bxd4 Bb4+ 12 Kf1 Bc5 is very good for black
while
10 Bd3 cxd4 11 Bxd4 Qc7 is not as bad for white
That is why 10 Bd3 is relatively better than 10 Be2

The position at move 10 is lost for white anyway.
8 b3 and 9 c4 were serious mistakes, that weaken your position and lose valuable time. Do not move pawns when you still have undeveloped pieces on their starting squares.

@Senpai-Noticed Move 24. Bc4 - not that it would lead to a loss, but you missed a quick win - you could have checkmated your opponent's king in 2 moves. Such omissions in computer analysis are flagged as a blunder.

@Senpai-Noticed The @tpr colleague wrote everything correctly. It makes no sense to understand the lost positions. In such positions, you can even accidentally win (as a result of mistakes of your opponent), but the analysis of such a game will not teach you anything - you still cannot play like a computer.
