Answer :
It means that the variable is multiplied by the number.
Examples:
' 17k ' means ' seventeen times k ' .
' 44D ' means ' D multiplied by 44 ' .
' t/9 ' means ' t divided by 9 ' .
A number and a variable side by side indicate a product.
For example, 101a means the same thing as 101 · a.
In the same way, 39g + 6 means the same thing as 39 · g + 6.
