Unformatted text preview: He theorized that every integer greater than 5 is the sum of three prime numbers. Show that this is true for the integers from 8 through 20. 4. Heres a method for multiplying two numbers without a calculator. Its called duplation and mediation. Multiply 27 * 35. Take half of the first number (disregard any remainders) and double the second number: 13  70 Repeat the process until you get 1 on the left. 6  140 3  280 1  560 Cross out any pairs where the number on the left is odd. Add the remaining numbers on the right. 27  35 13  70 6  140 3  280 1  560 So, well ignore the 140 and add the rest of the numbers on the right: 35 + 70 + 280 + 560 = 945 Now do the multiplication to verify. Use this method to perform each of these multiplications. Show the steps. A. 96 * 53 B. 45 * 75 C. 28 * 19 5. Find b if 43 111 = b . You must give an explanation as to how you found b . Trial and error will not get you the points!...
