Explain how you reasoned to this expression. a⊙ b =Evaluate: ! 10⊙5! 21⊙23! a⊙a✦ Number yourselves off 1 to 4. Get into your expert groups.✦ In your expert group, investigate the given expressions and come up with a general rule for each.✦ When instructed to do so, return to your initial group and explain the rules you discovered.
