๐Ÿงฎ Addition (+)

  • Meaning: Putting two or more numbers together to find the total or sum.

  • Symbol: + (plus)

  • Example:
    5
    +
    3
    =
    8

    5 + 3 = 8

    5+3=8

  • Properties:

    • Commutative Property: Order doesnโ€™t matter โ†’ 4
      +
      6
      =
      6
      +
      4

      4 + 6 = 6 + 4

      4+6=6+4

    • Associative Property: Grouping doesnโ€™t matter โ†’ (
      2
      +
      3
      )
      +
      4
      =
      2
      +
      (
      3
      +
      4
      )

      (2 + 3) + 4 = 2 + (3 + 4)

      (2+3)+4=2+(3+4)

    • Adding Zero: Any number + 0 = the same number โ†’ 7
      +
      0
      =
      7

      7 + 0 = 7

      7+0=7

โž– Subtraction (โˆ’)

    9 โˆ’ 4 = 5

    9โˆ’4=5

  • Properties:

    • Not Commutative: Order matters โ†’ 8
      โˆ’
      3
      โ‰ 
      3
      โˆ’
      8

      8 โˆ’ 3 \neq 3 โˆ’ 8

      8โˆ’3๎€ =3โˆ’8

    • Subtracting Zero: Any number โˆ’ 0 = the same number โ†’ 6
      โˆ’
      0
      =
      6

      6 โˆ’ 0 = 6

      6โˆ’0=6

    • Subtracting a Number from Itself: Always 0 โ†’ 5
      โˆ’
      5
      =
      0

      5 โˆ’ 5 = 0

      5โˆ’5=0
