Building expressions in MV Workstation
Fast, nestable commands for writing structure: power, fraction, fraction_mixed, recurring, subscript, binomial and more. Anything can go inside them, to any depth.
Type the maths the way you write it and MV Workstation shows the exact answer, the working and, where it helps, a picture you can drag.
Things to try
| What it is | Type this |
|---|---|
| Power with a nested exponent | 2 power((x + 2)) |
| Fraction inside a fraction | fraction({a + b}, fraction(c, d)) |
| Mixed number | fraction_mixed(2, 1, 3) |
| Recurring decimal | recurring(0, 3) |
| Subscripts | x subscript(1) + x subscript(2) |
| Brackets printed, groups silent | 2 power(()) + 3 |
| Choose | binomial(5, 2) |
Functions
| Function | What it does | Example |
|---|---|---|
power(exponent) | Raises the thing just before it. Anything can go inside, to any depth: 2 power((x + 2)) is 2^(x + 2). Inner ( ) are printed, { } group without printing, and power(()) prints empty brackets. | 2 power({1/2} + {3/2}) |
subscript(index) | Puts a number or short name below the letter before it: x subscript(1) is x₁, a subscript(n) is aₙ. | x subscript(1) + y subscript(2) |
fraction(top, bottom) | A fraction with a real fraction bar. Top and bottom can be any expression: fraction({a + b}, fraction(c, d)). Brackets you type inside are printed, { } group without printing. | fraction({1 + 2}, fraction(2, 3)) |
frac(top, bottom) | A shorter way to type fraction(top, bottom). | frac(x, 2) |
fraction_mixed(whole, top, bottom) | A mixed number written the way it is on paper: fraction_mixed(2, 1, 3) is 2 and 1/3. It works with every fraction tool. (The older name mix() still works.) | fraction_mixed(2, 1, 3) + fraction_mixed(1, 3, 4) |
recurring(decimal, digits) | A recurring decimal with a bar over the repeating digits. recurring(0, 3) is 0.333…, recurring(1.5, 83) repeats 83. (The older name rec() still works.) | recurring(0, 3) |
percent(x) | x as a percentage: percent(25) is 25%, which means 0.25. Handy when the number is a longer expression. | percent({20 + 5}) |
factorial(n) | n factorial, written n!. factorial((n + 1)) is (n + 1)!. | factorial((3 + 1)) / factorial(3) |
ratio(a, b, c) | A ratio of two or three parts (the third is optional): ratio(2, 3, 5) is 2 : 3 : 5. | ratio(12, 18) |
binomial(n, k) | n choose k, typeset as two stacked numbers in brackets. binomial(5, 2) is 10. | binomial(5, 2) |
overline(x) | Draws a bar over its content: a line segment overline(AB), a conjugate, a mean. The value is the content's value. | overline(3 + 4) |
