This is just something that's really been bothering me for a while. 
On a microwave, if you press 6-0, it will cook for 60 seconds or one minute. And if you also press 1:00 it will cook for one minute, or 60 seconds, right?
Okay! So my question is, if you add 1:00 + 1:00 it is 2:00, right? So your food will cook for a total of two minutes. BUT if you add 60 seconds + 60 seconds it will only cook for one minute and twenty seconds. Even though 60 seconds is one minute?
I know, it's a very confusing question.
