The question is stephen read for 34 minutes on monday and 45 minutes on tuesday. use breaking apart to find how many minutes stephen read all togather. i am not sure what breaking apart means

Breaking apart means that you just take the tens from each number, and the ones from each number, then add them up.

The tens from your numbers are:
30 from 34
40 from 45

The ones from your numbers are:
4 from 34
5 from 45

Now, you have to add up the tens and ones separately.
30 + 40 = 70
4 + 5 = 9

Finally, you add up those 2 numbers that you got- 70 and 9

The Stephen read for 79 minutes total.
