Type in a math expression and the parser will solve it for you! Examples: 6.28 * (180 / 3.14) 3 + 4 * 2 / (1 - 5) ^ 2 1+1/(1+1/(1+1/(1+1/(1+1/(1+1/(1+1/(1+1/(1+1)))))))) - Φ 3+1/(6+9/(6+25/(6+49/(6+81/(6+121))))) - π (kind of) 1+1/1+1/2+1/6+1/24+1/120+1/720 - e I guess you could call these formulas “phi pie”. Hehe. :)
