This works because:
10a+b * 5 =
50a + 5b =
100(a/2) + 5b

602 = 10(60) + 2
(10(60) + 2) * 5 =
50(60) + 2(5) =
100(60/2) + 2(5) =
100(30) + 10 =
3000 + 10 =
3010

We can use a area model so 602 so which means 600 and 2 on top of the area and next to the area we write 4 and 1 so 600x4=2, 400 and 600x1=600 2x4=8 2x1=2 add all of the answers up 2, 400+600=3, 000+8+2=3, 010
