How do you round up or down when the last digit of significant digit is 5?
When the last digit of a significant digit is 5 and we need to round it, we follow a rule called "round half up". This means that we round the digit up to the nearest number if the digit before it is odd, and round down if it's even. For example, 2.5 would round up to 3, while 3.5 would also round up to 4.
