# Learn

When you count backwards from zero, you count in negative numbers, for example -1, -2 and so on.

Negative numbers are commonly used when talking about temperatures. One of the coldest temperatures recorded in Antarctica is -93.2℃!

## What are positive and negative numbers?

Any number above zero is a positive number. Positive numbers are written with no sign or a + sign in front of them and they are counted up from zero to the right on a number line.

Any number below zero is a negative number. Negative numbers are always written with a - sign in front of them and they are counted down from zero to the left on a number line.

Always look at the sign in front of a number to see if it is positive or negative.

Zero, 0, is neither positive nor negative.

Let ‘The Posh Pooch’ from BBC Supermovers explain negative numbers in an entertaining way, with this song and movement routine made for KS2 pupils.
