Single and Double Digit Multiplication Worksheets
How to Multiply Single and Double Digit Numbers - Multiplying two single-digit numbers can be a pretty simple task to perform. However, multiplying a single-digit number by a double-digit number can be a situation when things are taken up a notch on the level of difficulty. But still, it is also not that difficult of a task to do. While multiplying a double-digit number by a single-digit number, we just have to write them in a row, one below the other. Usually, we write the double-digit number above the single-digit number. After we write it in this manner, we simply multiply the single-digit number with both the digits of the double-digit number and write the answers below. Then we add the answers below in columns to obtain the final answer. Two double-digit numbers are multiplied in the same manner.
