Intro to College Algebra Assignment for 9/9

Finish the Four 4’s puzzle you started in class: Using four 4’s and any combination of operations, write ten expressions that each evaluate to the numbers 1 through 10 (and 11 through 15 if you’re interested in a challenge!). You must use exactly four 4’s (no more and no fewer!) and you may not use any other numbers than fours (so no powers of two or three).
