Subtracting Across Zeros — Easy Worksheet 1
Grade 2 · MathSheets Name: ____________________ Date: __________
Subtract. Regroup across the zeros when you need to. The same kind of problem comes in different shapes.
How to solve
When a place has 0, borrow from the next place to the left. 400 is 3 hundreds, 9 tens and 10 ones. So 400 − 158: 10 − 8 = 2, 9 − 5 = 4, 3 − 1 = 2, and the answer is 242.
Example
Subtract.
Answer: 28
Warm-up
Not quite. The answer is
💡 Ones: 0 is less than 1, so regroup 1 from the tens. Now 10 − 1 = 9. Tens: the 5 is now 4. 4 − 2 = 2. So 50 − 21 = 29.
✓ Correct!
