Dear Dr. Data

Greeting to you! We are the students in Mr. Styes' class. We have some math questions for you that we need your help with. Here they are:

Why do the numbers on each side of an equation have to balance? Ex: 5+5+5=7+8

Why can a t-table (aka input-output table) be standing up or lying on its side? And we're wondering if there is ever a limit to how many numbers you can put on a t-table. In other words, will there ever be a time when you run out of numbers to put on it?

We know we are really bright mathematicians because we do Algebra in 4th grade. Will we get to do it in 6th grade too?

Thanks for your help, Dr. Data. We'll be looking forward to your response.

Until next time!
Mr. Styes' 4th grader class.
