  • The properties of operations are: identity property, inverse property, commutative property, associative property, and distributive property.
  • Additive identity- the sum of a number and 0 is the same number
    Ex. 9+0=9
  • Multiplicative identity- the product of a number and 1 is the original number
    Ex. 5x1=5
  • Additive Inverse- the sum of a number and its opposite/inverse is 0
    Ex. -9+9=0
  • Multiplicative inverse- the product of a number and its reciprocal is 0
    Ex. 5 × 1/5 = 1
  • Commutative property of addition- changing the order of addends does not change the sum
    Ex. 4 + 2 = 2 + 4
  • Commutative property of multiplication- changing the order of factors does not change the product
    Ex. 4 × 3 = 3 × 4
  • Associative property of addition- changing the grouping of addends does not change the sum.
    For example, (2 + 3) + 4 = 2 + (3 + 4).
  • Associative property of multiplication- Changing the grouping of factors does not change the product.
    For example, (2X3)x4 = 2x(3x4).
  • Distributive property- multiplying a value by its sum or difference, you will get the same result.
  • variable- a letter used to represent one or more numbers in an expression or equation
  • constant has a fixed value that does not change.
  • algebraic expression- a variable, a number, or a combination of both that are related by any of the fundamental operations of algebra
  • equation- a mathematical statement indicating that two algebraic expressions are equal
  • sequence- a set of numbers written in a special order by the application of a definite rule
  • term- each number or expression in a sequence
  • formula for average speed- as=td/tt
  • surface area- the sum of the areas of the base(s) and the lateral faces of a space figure
  • surface area= lateral area + base areas
  • sa of rectangular prism=2lw+2lh+2hw
  • sa of cube= 6s²
  • sa of sphere= 4πr²
  • sa of cone= πrs + πr²
  • SA of Cylinder = 2πrh + 2πr²
  • SA of Triangular prism = lp + bh
  • Volume of cylinder = πr²h
  • Volume of cone: πr²h/3
  • Volume of sphere: 4/3 πr²
  • Volume of pyramid: 1/3 bh
  • Volume of triangular prism: (bxh)/2 h
