Show how the following floating point arithmetic is performed: $($Operations has tobe performed by converting the decimal numbers into IEEE format$)$

a$)0\mathrm{.}7744$ x $10^2+0\mathrm{.}6666$ x $10^1$

b$)24\mathrm{.}68$ x $10^6-34\mathrm{.}28$ x $10^1$

c$)32\mathrm{.}85$ x $2^26-2\mathrm{.}879$ x $2^4$

d$)(1\mathrm{.}24$ x $10^1)$ x $(2\mathrm{.}34$ x $10^2)$

e$)(454\mathrm{.}45$ x $10^(-1))/(342$ x $10^(-2))$
