# Number @ LieElement -- formal multiplication of a number and a Lie element

- Operator: @

## Description

Formal multiplication by scalars. See the documentation of the formal Lie multiplication for more information.

    i1 : L = lieAlgebra{a,b}

    o1 = L

    o1 : LieAlgebra

    i2 : (2@a)++(2@a)

    o2 = 2 a + 2 a

    o2 : L
