Ordering Numbers

• Numbers can be ordered from least to greatest (smallest to biggest) Example: {-5,0, 1, 2,4}

• They can also be ordered from greatest to least (biggest to smallest) Example: {10, 9, 4, 0, -1, -5}

Multiple Choice

Order from least to greatest:
[10, -5, 3, 16, -1, 0, 1]

• -1, -5, 0, 1, 3, 10, 16
• 16, 10, 3, 1, 0, -1, -5
• -5, -1, 0, 1, 3, 10, 16
• 0, -1, 1, 3, -5, 10, 16

Multiple Choice

Order from least to greatest:  -5, -17, 3, 0 

• 3, 0, -5, -17
• 3, 0, -17, -5
• -17, -5, 0, 3
• -5, -17, 0, 3

Absolute Value

• The distance between a number and zero Example: l-6l= 6 and l6l=6

• opposites are numbers that are the same distance from zero in opposite directions. Example: 3 and -3 are opposites, they both have a distance of 3 from zero.
