Answer #1

Adding doubles is the same thing as multiplying by 2. Instead of memorizing the two tables, all you have to do is add the same number twice. Examples: 4*2=4+4=8, 7*2=7+7=14, etc.

Q1) How would you declare an array of doubles called myDoubles? Arrays can be initialized in one of two ways. In one method, the array elements are placed in a list enclosed in curly braces after the array name deﬁnition. For example, the code below creates an array of ints with 3 elements: 1, 2 and 3. int[] a = {1, 2, 3, 4}; We can also initialize an array with a new construct, indicating how many elements we want...

You know that to multiply a binary integer by 16, all you have to do is shift the value over by 4 bit positions -- which in hardware can literally be done without a function unit simply by connecting bus wires such that bit k goes to position k+4 and positions 0-3 are connected to ground. Well, it's harder to multiply by 15. However, by using Booth's algorithm, a single 32-bit add/subtract ALU is sufficient to implement multiply of a...
