FAQ

Everything you need to know about this question

What happens when I subtract 1 from any number?

+

When you subtract 1 from any number, you get the previous number in the counting sequence. Think of it as going one step backward on a number line.

Why does only the last digit change when subtracting 1?

+

The last digit represents the ones place. Since we're subtracting just 1 unit, only this digit needs to change. The other digits (tens, hundreds, thousands) stay the same.

What if the ones digit is 0 and I subtract 1?

+

Great question! If the ones digit is 0, you need to borrow from the next place value. For example: 5160 - 1 = 5159 (the 6 becomes 5, and 0 becomes 9).

How can I check if my subtraction is correct?

+

Use addition to check subtraction! Add 1 to your answer. If you get back to the original number, you're correct. For this problem: 5161 + 1 = 5162 ✓

Is there a faster way to subtract 1 mentally?

+

Yes! Just think: "What number comes right before this one?" For 5162, the number right before it is 5161. This works for any subtraction by 1.
