Stack the number with the most digits on top. Multiply the same as multi-digit whole numbers, regrouping when necessary. Count the number of digits after the decimal point for each factor. Put the same number of digits behind the decimal point for the product.Long Multiplication with Negative Numbers. When performing long multiplication you can ignore the signs until you have completed the standard algorithm for multiplication. Once you complete the multiplication follow these two rules: If one number is positive and one number is negative make the product negative.One can check using the standard algorithm to multiply two 2-digit numbers that 25 times 18 is 450.
