Spiegazione passo passo

1. Rewrite the numbers from top to bottom, aligned by their place values

Place value	tens	ones

	2	4
		8
-	1	2

2. Subtract the numbers using long subtraction method

Because the upper digit (4) in the ones column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (14).

Place value	tens	ones
	1	14
	2	4
		8
-	1	2

Subtract the numbers in the ones column from the top number:
14-8-2=4

Place value	tens	ones
	1	14
	2	4
		8
-	1	2
		4

Subtract the numbers in the tens column from the top number:
1-1=0

Place value	tens	ones
	1	14
	2	4
		8
-	1	2
	0	4

The solution is: 4
