Rounding is figured out by deciding where in two brackets the portion of the number you want to round lies. So, if you were rounding by 100, then if it was anywhere between 1-50, you would round down. 51-99, you would round up. 866 is in the second bracket, so you would round up to 900.
Well, isn't that a lovely number! When we round 866 to the nearest hundred, it becomes 900. Just imagine that number surrounded by happy little clouds and trees, feeling all cozy and rounded. It's important to remember that numbers can change a bit, but they're still special in their own way.
