Key Points to Remember

Essential concepts to master this topic

Predecessor Rule: The predecessor is always one number less
Technique: Subtract 1 from the given number: 35,001 - 1 = 35,000
Check: Verify that 35,000 + 1 equals the original number 35,001 ✓

Common Mistakes

Avoid these frequent errors

Adding 1 instead of subtracting
Don't add 1 to find a predecessor = 35,002 is the successor! This gives the number that comes after, not before. Always subtract 1 to find the number that comes before.

FAQ

Everything you need to know about this question

What's the difference between predecessor and successor?

A predecessor is the number that comes before (subtract 1), while a successor is the number that comes after (add 1). Think of it like walking backwards vs forwards on a number line!

Why is the answer 35,000 and not 34,999?

Because we start with 35,001 and subtract 1. The calculation is $35,001 - 1 = 35,000$ . Remember, we're finding what comes immediately before 35,001.

Does every number have a predecessor?

Yes! Every whole number has a predecessor. Even large numbers like 35,001 follow the same rule: subtract 1 to find the number that comes before it.

How can I check if my answer is correct?

Simple! Add 1 to your answer. If you get the original number, you're right! For example: $35,000 + 1 = 35,001$ ✓

What if the number ends in zeros like 35,001?

The same rule applies! Don't let the zeros confuse you. Just subtract 1 normally: $35,001 - 1 = 35,000$ . The pattern works for any number.
