can you just give me a math riddle that's understandable to 7 th grade

Cent + Cent+ Scent=35128

What do the letters stand for?

I think the answer is t=6 e= 0 n=4 and 3 c=6 s=2

Of course! Here's a math riddle for you:

Riddle: I am an odd number. Take away one letter and I become even. What number am I?

To solve this riddle, let's break it down. It says that the number is odd, but if you take away one letter, it becomes even. So, let's think about a word that represents an odd number but becomes an even number if we remove one letter.

The word we are looking for is "seven." If we remove the letter "s," it becomes "even," which is an even number.

Therefore, the answer to the riddle is the number 7.
