Product Information

Long multiplication with decimals using the standard algorithm has a few simple additional rules to follow. Proper fraction button and Improper fraction button work as pair. When you choose the one the other is switched off. Long multiplication means you're doing multiplication by hand. The traditional method, or Standard Algorithm, involves multiplying numbers and lining up results according to place value. These are the steps to do long multiplication by hand: Proper fraction button is used to change a number of the form of 9/5 to the form of 1 4/5. A proper fraction is a fraction where the numerator (top number) is less than the denominator (bottom number).

Arrange the numbers one on top of the other and line up the place values in columns. The number with the most digits is usually placed on top as the multiplicand. These are same steps the long multiplication calculator uses to show the work for a multiplication problem. In the work, the calculator supplies a zero value in place values where the shift step happens. Many people who work a multi-digit multiplication problem by hand will simply leave a space here for brevity, but offsetting with zeroes helps to avoid calculation errors during the addition step by keeping the place values aligned. If you hover over one of the step products in the multiplication calculator's work area, it will show you the intermediate multiplication calculation used to generate it. More Resources for Learning Multi-Digit MultiplicationInsert a decimal point in the product so it has the same number of decimal places equal to the total from step 1. Proceed right to left. Multiply the ones digit of the bottom number to the next digit to the left in the top number. If you carried a digit, add it to the result and write the answer below the equals line. If you need to carry again, do so.

When you've multiplied the ones digit by every digit in the top number, move to the tens digit in the bottom number.Multiply as above, but this time write your answers in a new row, shifted one digit place to the left. Starting with the ones digit of the bottom number, the multiplier, multiply it by the last digit in the top number
