Leave one variable blank, and FormulaBox solves for it. Type any formula, fill in the numbers you know, and the blank one is worked out: the exact answer where there is one, and its decimal value. • Any formula, typed or pasted: use the math keyboard, or paste LaTeX. No LaTeX needed. • A library ready to use: mathematics, statistics, physics, finance, chemistry, construction, queueing theory, atomic and nuclear physics. Pick a formula and compute. • Constants already in: the speed of light and others are filled in, so you enter only the rest. • Simplify in one step: fractions, roots and powers made simple. • Your own formula box: save the formulas you use, with tags and notes, and share them as a link, LaTeX or a picture. • Two pages on big screens: on iPad and iPhone Duo, the formula on one page, the answer on the other. • Choose how many decimal places in Settings.
