We spend a lot of time focused on multiplication tables, and getting past the stages of memorizing math facts is an important milestone. By the time we are working with multi-digit problems, we’re starting to deal with algorithms, the series of steps, necessary to solve problems. Fortunately, learning multi-digit addition and multi-digit subtraction, even with regrouping, is usually achieved without too much difficulty.
The steps for multi-digit multiplication require are a bit more demanding… In fact, it has all the fun of multi-digit addition on steriods right along with the twists multiplication brings as well. However, I’ve got a great tool that should take away some of the long multiplication anxiety…

Put a couple of numbers in there and hover your mouse over the work produced by the calculator… You’ll see what parts from the multiplicand and the multiplier are used to create each step, and it clearly shows how the place values are preserved as we work through the multiplier digits. It’s a great tool for developing an understanding of the conventional steps for multi-digit multiplication.
