We definitely approach these problems differently. I will have to look again to see why I thought I needed that last equation.

I found your first puzzle easier to solve than your second puzzle, but I eventually was able to figure it out. I really like these puzzles a lot especially when only 8 or 9 equations are used. Can you solve mine? Digits -4, -3, -2, -1, 0, 1, 2, 3, 4 are disguised.

I almost always do it sum first now. See this one: bsky.app/profile/davi...
x^2+30x+224
Yes this looks like fun!
20+10=30, 20×10=200 too low but close
21+9=30, 21×9=189 wrong way!
19+11=30, 19×11=209 aha better
18+12=30, 18×12=216 close
17+13=30, 17×13 well that’s not even
16+14=30, 16×14=224 yay!
(x+16)(x+14)
This is a great example of using this method!
