Answer: They are the mathematical symbols of pi, infinity, and square root. I'm not a math person, and this is only what I read regarding calculating the square root of pi: "Pi is the constant equal to the ratio of the circumference of a circle to its diameter. The number (3.14) has been calculated to over one trillion digits beyond its decimal point. Calculations can continue infinitely without repetition or pattern, because Pi is an irrational number." I'm sure the more scientifically-minded members here can provide a better explanation. I interpreted the symbols on Little Jack's T-shirt as meaning his future has infinite possibilities.
