What number follows 70,099?
A predecessor comes before a number (subtract 1), while a successor comes after a number (add 1). Think of it like standing in line - predecessor is behind you, successor is ahead!

Remember: "Before means subtract" and "After means add". The word "before" in the question tells you to subtract 1!
Yes! Every whole number has a predecessor (except 0). Just subtract 1 from any number to find what comes immediately before it on the number line.
No problem! When subtracting 1 from numbers ending in zero, you get 9 in the ones place. For example: 67,100 - 1 = 67,099, just like 20 - 1 = 19.
