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 from zero to the right.
Any number below zero is a negative number. Negative numbers are always written with a '-' sign in front of them and they are counted from zero to the left.
Always look at the sign in front of a number to see if it is positive or negative.
Positive numbers get higher the further we move right, so 5 is more than 2.
Negative numbers get lower the further we move left, so -5 is less than -2.
Which word, 'higher' or 'lower', would fit correctly in each of these gaps?
a) -7 is ............... than -1

c) -136 is ............... than -36
a) -7 is lower than -1
b) + 62 is higher than -71
c) -136 is lower than -36
