The document explains how to perform 2-digit multiplication. It goes through the step-by-step process, which includes: 1) lining up the numbers with their place values, 2) multiplying the ones place and carrying numbers, 3) multiplying the tens place and using a placeholder zero, and 4) adding the partial products together to get the final product. The example shown is 26 x 12 = 312, and each step of the multiplication is demonstrated.
