Let's practice stacking with this problem, 14 x 2. Sometimes this remainder is added to the quotient as a fractional part, so 10 / 3 is equal to 3+1/3 or 3.33, but in the context of integer division, where numbers have no fractional part, the remainder is kept separately (or exceptionally, discarded or rounded). When you multiply stacked numbers, you start with the right digit in the bottom number of the problem. This means, 3 6 = 18 pencils. We're done! If you can multiply these problems, you can multiply anything. For example, if there are 3 packs of pencils and each pack has 6 pencils, let us find the total number of pencils. Now that we multiplied with the third digit Now that we multiplied with the third digitwe placed the product two spaces to the left. It's a good idea to mark the space you left blank.
