To multiply using the line method, begin by setting up the problem so you can solve it with ease. You’ll need to know how many places are in your first number and what digit is in each place. For example, if you’re multiplying 34×12, you would determine that the first number, 34, has a 4 in the ones place, and a 3 in the tens place. Then draw parallel lines at a 45º angle slanting right to represent the tens place of your first number, so for 34 you’d draw 3 parallel lines. Next draw parallel lines to represent the ones place of your first number, which is 4 lines for 34, placing these to the right of the tens lines and leaving some space between them so you can tell them apart. Now you’ll determine the place values of your seconds number in the same way as you did for your first number, so for 12, you’ll have a 2 in the ones place and 1 in the tens place. Once again, draw parallel names in a different color for the second number, making the number of lines match the digits. So for 12, you’d draw 1 parallel line in the tens place and 2 parallel lines for the 2, below the tens line. Finish setting up the problem by drawing dots on each point where the lines intersect. Now it’s set up, read on for help on solving the problem!
