When im doing decimals for the answer (example) lets just say 83.467 is my answer when i simplify it do i completly take off that last number (example: 83.467 -> 83.46) or so i round it so it would be (example 83.467 -> 83.47)?

Answer 1

if it's above five you round up but if it's below five you round down.

if your using money you always round up because in the real world you can't round down with money
