�A negative number is less than zero � The bigger a negative number is the less it’s worth � For example -100 is less than -1 Examples -1 -2 -4 -15 *Any negative numbers

� Negative numbers are always on the left � The zero separates positive and negative numbers � Negative numbers are less than positive numbers Examples � -3< 2 � -8<7 � 9>-15

� The opposite of a positive number is a negative number (vice-versa) � For example the opposite of 3 is -3 or the opposite of -8 is 8 Examples � -2 to 2 � -9 to 9 � 5 to -5 � -6 to 6 � 4 to -4

� The opposite of a negative sign(-) is a positive sign(+) Examples -4=the opposite of 4 -5=the opposite of 5 -6=the opposite of 6 -15=the opposite of 15

� By organizing negative numbers you have to put them for smallest to greatest or greatest to smallest � But the bigger a negative number the smaller it is � For example -15 is smaller than -7 Examples smallest to greatest � -15, -13, -10, -5 � -20, -12, -9, -2 � -3, -2, -1 Greatest to smallest � -2, -10, -12, -17 � -3, -9, -18, -25 � -5, -6, -19, -28

� An absolute number can be a positive/negative number � The value of x is the distance of zero Examples � Zero is an absolute number � 5 � 6 � 3 � Only positive numbers can be absolute numbers

� If there are two Examples numbers we can � 8=8 compare them. One � 9<12 number is either � -2>-17 greater than, less than or equal to the � 0=0 other number � -19<-8 � The absolute value of a number is the positive value with the same magnitude.

� Every value has an absolute value sign � When plotting numbers on a number line you have to know how far way it is from zero � If the value is negative you go left and if it’s positive you go right Examples
