Russian peasant multiplicationThe Russian peasant multiplication, also called the Russian peasant algorithm, uses a halving and doubling method to multiply whole numbers I will illustrate the method with two good examples that you should study carefully. When halving, disregard any remainder. Just put the quotient in the halving column When the number in the halving column is 1, cross out all rows that have an even number in the halving column the answer is found by adding the remaining numbers in the doubling column Example # 1: 11 × 12 Halving Doubling 11 × 12 5 × 24 1 × 96 The sum is 12 + 24 + 96 = 132 Example # 2: 37 × 42 Halving Doubling 37 × 42 9 × 168 1 × 1344 The sum is 42 + 168 + 1344 = 1554 Your turn! try a few multiplication using the Russian peasant multiplication Need a Quick Answer to your Math Problems?
