Math

• The word integer, which means whole or intact, is a special set of numbers comprising zero, positive numbers and negative numbers.
• Percentage - part or proportion of the base, usually beside the word "is"
• Rate - also called percent which has the (%) sign
• Base- the entire original amount, usually comes after the word "of"
• The word "of" represents multiplication
• The word "is" represents equals
• To find the percentage you need to find the base
• P = R x B

  R = P ÷ B

  B = P ÷ R
• Positive + Positive = Positive
• Negative + Negative = Negative
• Positive + Negative = the larger sign of the absolute value number
• Change the sign from "+" to "-" if there are different integer signs
• 2n + 3 = is a algebraic equation
• 3r + 2 is a algebraic expression
• 2n + 3

  2n is the coefficient
• Variable is an alphabet or term that represents an unknown number or unknown value
• Volume of a Cone Formula

  V = (1/3)πr²h, where V is the volume, r is the radius, and h is the height
• Volume of a Sphere Formula

  V = (4/3)πr³, where V is the volume and r is the radius
• Volume of a Rectangular Prism

  V = l × w × h, where V is the volume, l is the length, w is the width, and h is the height
• Volume of a Cube Formula

  V = s³, where V is the volume and s is the side length
• Volume of a Rectangular Pyramid Formula

  V = (1/3)lwh,
• Volume of a Cylinder Formula

  V = πr²h, where V is the volume, r is the radius, and h is the height
• Definition of Volume


  The amount of 3D space a shape occupies or the amount of material it contains, typically measured in units such as cubic centimeters (cm³), cubic meters (m³), or liters (L)
• Cubic Meters


  A unit of volume, equal to the volume of a cube with 1 meter (m) on each side, equivalent to 1000 liters (L) or 1,000,000 cubic centimeters (cm³)
• Partitive Proportion


  A method of solving percent problems by dividing the part being measured from the whole, and then multiplying by 100 to find the percentage, using the formula Part / Whole = (Part / 100)
• Inverse Proportion


  A relationship between two variables where as one variable increases, the other decreases, and vice versa, described by the equation y = k/x, where y is the decreasing variable and x is the increasing variable
• Direct Proportion


  A relationship between two variables where as one variable increases, the other also increases, and vice versa, described by the equation y = kx, where y is the increasing variable and x is the increasing variable
• Circumference


  The distance around a circle, calculated by 2 * π * Radius or π * Diameter
• Diameter


  The longest distance across a circle, passing through its center
• Circle


  a set of points equidistant from a central point (the center)
• Center


  The point where the circle's diameter is vertical
• Sector


  A region of the circle bounded by a central angle and a chord
• Arc


  A part of the circle's circumference, measured in degrees or radians
• Chord


  A line segment within the circle, connecting two points on its edge
• Radius


  The distance from the center to the circle's edge
• Radius Formula

  Radius = Diameter / 2 (or Circumference / (2 * π))
• Circumference Formula

  C = 2 * π * Radius (or C = π * Diameter)
• Value of π

  π is an irrational number, approximately equal to 3.14 or 3.14159 (or more decimal places)
• Diameter Definition


  The longest distance across a circle, passing through its center
• Diameter Formula


  D = 2 * Radius (or D = C / π)
