Snapshot: 7A Four 4's Challenge

The seventh grade kicked off the school year with the Four 4's challenge. They had to use four 4's to make equations for each number between 0 and 50. They could use the operations add, subtract, multiply, divide, parentheses, exponent, and square roots. They were introduced the concept of factorials (4! = 4 x 3 x 2 x 1 = 24). We found patterns to find families of answers and exercised our understanding of order of operations to find solutions. The even numbers were easier to find and we are now left with the challenge of finding solutions for 31, 33, 37, 39, and 41.  

Can you figure out the missing numbers?
