Long multiplication and long division were never too popular at school, unless of course they were made considerably easier by involving multiplication or division by 10. So this week’s exercise is a simple (?) calculation involving multiplication by TEN.
Usual letters-for-digits rules apply: a letter stands for a particular digit throughout, and different letters stand for different digits. The letters already shown can, of course, also be used to fill the blanks, but need not be.
