Arithmetic and number sense in MV Workstation

Whole numbers, decimals, fractions, percentages, order of operations, factors and multiples, rounding, powers and roots.

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

Function	What it does	Example
`abs(x)`	Absolute value: how far x is from zero. Shown as \|x\|.	`abs(3 - 8)`
`sign(x)`	-1, 0 or 1 depending on the sign of x.	`sign(-5)`
`floor(x)`	Round down to a whole number.	`floor(2.7)`
`ceil(x)`	Round up to a whole number.	`ceil(2.1)`
`trunc(x)`	Drop the decimal part: trunc(-2.7) is -2.	`trunc(-2.7)`
`round(x, digits)`	Round to the nearest number, halves away from zero. digits is how many decimal places to keep (default 0).	`round(3.14159, 2)`
`min(a, b)`	The smaller of two values.	`min(3, 7)`
`max(a, b)`	The larger of two values.	`max(3, 7)`
`gcd(a, b)`	Greatest common divisor: the largest whole number that divides both. Used to simplify fractions.	`gcd(12, 18)`
`lcm(a, b)`	Least common multiple: the smallest positive number both divide into. Used to add fractions.	`lcm(4, 6)`
`sqrt(x)`	Square root. You can also type √x.	`sqrt(49)`
`root(x, n)`	The n-th root of x. root(27, 3) is the cube root of 27.	`root(27, 3)`
