Reflection of Maths

For maths this week I looked at Rounding decimals.

Adding and subtracting decimals is quite easy once you learn how to do it. 

For Example:
3.d.p
33.456375 rounded to the third decimal place. What you have to do is...

*scientist voice* when you round it to the third decimal place you check the number before it to see if it is over or under five and in this case the number before it is 3 so it is under five so the rounded number is

33.456 BUT if it was over five the last number would be one number up like this 33.457.

Thx for looking at my post!!
