Perfect squares are the squares of the integers, or the product of an integer with itself. Learn the definition, formula, list, tips and tricks, facts with examples.
It's good to know that all perfect squares end with 1, 4, 5, 6, 9, or 00. That's how you can perform a quick first selection and decide which number can and cannot be a perfect square. If your number ends with 1, 4, or 9, its ten's digit should always be even (0, 2,...
Going back to the basic concept of multiplication though the use of counters or pictures shows how perfect squares are created and why they are named. Answering one of the original questions about why a doubles fact is called a square requires a return to the visualization of multiplication. An...
