Compare and order integers

key notes:

Understanding Integers:

• Integers include all whole numbers, both positive and negative, as well as zero (e.g., -3, -2, -1, 0, 1, 2, 3).
• Integers do not include fractions or decimals.

Number Line:

• Use a number line to visualize integers.
• The left side of the number line represents negative integers, while the right side represents positive integers.
• Zero is in the middle and acts as the dividing point.

Comparing Integers:

• To compare two integers, determine their position on the number line:
  • The integer that is further to the right is greater.
  • The integer that is further to the left is smaller.
• Symbols used for comparison:
  • Greater than (>): e.g., 3 > -1
  • Less than (<): e.g., -2 < 2
  • Equal to (=): e.g., -1 = -1

Ordering Integers:

• When ordering integers, list them from least to greatest or greatest to least.
• For example, to order the integers -2, 3, 0, and -5 from least to greatest:
  • -5, -2, 0, 3.
