Main Question or Discussion Point

Will someone please remind me why int from 0 to 1 of 5 equals 5, when the sum of the values 5 at, say 1.1, 1.2, 1.3, 1.4, 1.5, 1.6 is > 5? I lost this fundamental understanding today and want to gain it back.

Thank you

If you go back and think of the integral as an area under the graph, then you see that 5 at 1.1, 1.2, 1.3, ... is always 5, but the boxes are only 0.1 wide, so the area in each of them is only 0.1*5. Add up the 10 boxes and you get the total area which is 5.
