Question

A cray scientific computer can do a simple addition in 130x10^-12 seconds (130 picoseconds).how many additions can the cray computer do in 1 minute?
Please give the answer in engineering notation, cant seem to understand.

Answer 1

Didja mean scienfici notation

ok, so 1minute=60 seconds

time/time per calculation=number of calculations
time=60
time per calculation=130*10^-12
60/(130*10^-12)=
(6/13)*(1/10^-12)
x^-m=1/(x^m)
(6/13)(1/(1/10^12))=
(6/13)(10^12)=
0.4615*10¹² calculations per minute
