Comments inside, suggest you write your guesses down so you can quickly narrow answers to the accuracy desired. Don't forget to use decimal numbers when you get close, see standard.. CCSS.Math.Content.8.NS.A.2 Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., π2). For example, by truncating the decimal expansion of √2, show that √2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations. This is currently set to E <0.001
