Use cyclical coding (A-1,B-2…,Y-25, Z-0) that will shift each given letter 6 positions to code CHE.

Using 2's complement representation, perform the following arithmetic subtraction (- 00001001) - (- 00001110) = a. 11111011 b. 00000101 c.111111011 d. 100000101

In single precision (IEEE-754 standard), 8 bits are used for storing the exponent (the bias is 127), and 23 bits are used for storing the mantissa.  (a) What are the smallest and the largest positive numbers that can be stored in single precision? (b) What is the smallest value of the mantissa that can be stored?

Use exponent rules to evaluate the following to a single power of POSITIVE 10. Use the (^) to indicate power when writing your answer 1015 x 10-6 × 10-14 10-6x10-12 ×10° 10-3x1017
