Subtracting 2-Digit Numbers (without borrowing)
To subtract a 2-digit number from another 2-digit number, fi rst subtract the
ones and then the tens.
Let’s subtract 25 from 67.
T O T O
6 7 6 7
– 2 5 – 2 5
2 4 2
Step 1: Subtract the ones. Step 2: Subtract the tens.
7 – 5 = 2 6 – 2 = 4
So, 67–25 = 42.
4. Subtract the given numbers.
T O T O T O
(a) (b) (c)
6 7 8 4 5 6
– 4 5 – 2 4 – 3 0
