here is a nice simple way to add hours and minutes together

lets add 1hr & 35 mins and 3 hrs & 55mins together

how to do it simple

Take these two times as simple natural numbers like 135 and 355

Add them

we get 135 + 355 = 490

Now add a constant number 40 to it:

we get 490+ 40 = 530

so the time is 5 hrs and 30 mins ....


Amazing but it always works:

Am I crazy or does that only apply when the minutes add up to more than an hour?

take 4:40 and 3:10 your way would get them 440+310=750 and then add 40 so they'd be 790

Off course... its only for the problems when the minutes go beyond 60.
Otherwise use normal addition. As simple as that!
