... • Suppose n is even, n = 2m • To compute a∙b • Write a = a1∙2m + a0, b = b1∙2m + b0, where a1, a0, b1, b0 are m-bit numbers (numbers < 2m) – the first and last m bits of a and b a∙b = a1b1∙22m + (a1b0+a0b1)∙2m + a0b0 = a1b1∙(22m+2m) + (a1-a0)(b0-b1)∙2m + a0b0∙(2m+1) Only 3 m-bit multiplications!!! ...

... After we change double signs into a single sign we may then, organize the numbers in columns, depending on what sign is in front of them. We would then add the numbers that are in the same columns together. Next, we can subtract the totals from each other and the answer would include the sign of the ...

... When a counting number can be described by several factor pairs, then it is composite; when a counting number can be described with only by one factor pair, then it is prime. The numbers 0 and 1 are considered neither prime nor composite since there are an infinite number of factor pairs that have t ...

... 4. We need to find out how many of the numbers 0 through 39 are solutions to the equation x 2 =1 in Modulo 40. We could square all 40 numbers and see if these squares have a remainder of 1 when divided by 40. It might be obvious that the solutions must be odd numbers, which would narrow it down to 2 ...
