Basic Math/A Simple Question...


Hi John,

A friend asked me a question - What is a number between 3 and 5?

I said 3.  Is the only answer (as in whole number) 4?

I realise that I am probably a silly question though I've been thinking about it for quite some time now.

Many thanks


Hello, Stephen.

Yes, the only whole number between 3 and 5 is 4, though there are an infinite number of real numbers (all possible fractions, decimals, etc.) between those two points. Such possible real numbers would include 3.0005, 3.25, 4.484377383395373993593894839999993331, and 4.75.

I can help you solve problems involving fractions, decimals, ratios, and algebra. I can teach you how to do math faster, and even in your head. I can teach math definitions, and help you study, if necessary. Please do not ask any graphing, trigonometry, or calculus questions. Try to work through homework questions before asking for assistance.


I routinely process numbers of all kinds in my head, without need of a calculator.

I was an A math student while in high school.
