About this app
Two-Digit Multiplication is an interactive elementary math app that explains the standard column method through place value. Explore an area-style model that splits both numbers into tens and ones, see the four partial products grouped into two rows, and learn why the second row shifts when multiplying by tens. A practice mode lets learners complete the partial products for four fixed problems.
