I'm confused..!

Question

I'm doing this math crossword puzzle and it says the page asks for "digits decrease by a constant amount". What does that mean and how do it do it? I already have the first and last letter, 5?3. Its a three digit number.

Answer 1

In Mathematics we use the term "constant" to refer to something that stays the same and a " variable" is something that changes.

A constant is just another way of saying "number" . A number like 5 will always be 5 so we call it a constant. It is constantly the same

So if a problem says "digits decrease by a constant amount"

it just means that the digits can both be subtracted by the same number (constant) because a decrease is subtraction
