Here, you'd want to choose a variable, for example z, and multiplying this by the given constant, 6, would give the product z×6. The convention would be to place the coefficient in front of the variable, such as 6×z, and to omit the multiplication symbol which is implied with the expression, 6z.
Hope this helps.
