You see up to this point algebra has been very linear. You can tell what number to use next to solve an equation just by looking at it. Students might even feel a little joy and mastery and we throw this this curve ball.

2x = 8
divide by 2 the opposite of multiplying

x+2=8
subtract 2 the opposite of adding

x^5=32
take the fifth root the opposite of raising to a fifth power

x²+4x-60=0
(x ?)(x ?)=0

Guess.

I think to them it feels like we are going backwards, you know? 3/
