For matrices, the function is evaluated element wise. ## Syntax ```js math.add(x, y) math.add(x, y, z, ...) ``` ### Parameters Parameter | Type | Description --------- | ---- | ----------- `x` | number &#124; BigNumber &#124; Fraction &#124; Complex &#124; Unit &#124; Array &#124; Matrix | First value to add `y` | number &#124; BigNumber &#124; Fraction &#124; Complex &#124; Unit &#124; Array &#124; Matrix | Second value to add ### Returns Type | Description ---- | ----------- number &#124; BigNumber &#124; Fraction &#124; Complex &#124; Unit &#124; Array &#124; Matrix | Sum of `x` and `y` ## Examples ```js math.add(2, 3) // returns number 5 math.add(2, 3, 4) // returns number 9 const a = math.complex(2, 3) const b = math.complex(-4, 1) math.add(a, b) // returns Complex -2 + 4i math.add([1, 2, 3], 4) // returns Array [5, 6, 7] const c = math.unit('5 cm') const d = math.unit('2.1 mm') math.add(c, d) // returns Unit 52.1 mm math.add("2.3", "4") // returns number 6.3 ``` ## See also [subtract](subtract.md), [sum](sum.md)
