Please explain your answer for each

Floating point operations. (a) Use decimal (base-10) values (2.851 times 10^-1 and -9.854 times 10^-1) to illustrate the floating-point addition algorithm step by step. List the name/action of each step, and illustrate the step using the given value. Your result should have 4 significant digits. (b) Use the same value as (a) to illustrate the floating-point multiplication algorithm step by step. Again, the result should have 4 significant digits. (c) Using binary values -1.11110011 times 2^-3 and 1.10001111 times 2^2 to illustrate the floating-point multiplication algorithm step by step. Leave the result formatas the input data
