_____

If we use : to separate columns with different place value, this can be looked at a couple of ways.

Subtraction by addition

2 : 4 + 0 : 2 = 3 : 1 . . . . . make the 1s place match

3 : 1 + 1 : 0 = 4 : 1 . . . . . . make the 5s place match

The total amount added was 0:2 +1:0 = 1:2.

Subtraction using borrowing

4 : 1 - 2 : 4 = (4-1) : (5+1) - 2 : 4

= (4-1-2) : (5+1)-4 = 1:2
