Estimation 
The process of finding an estimate or approximation
Estimate 
A value derived from the best information available that is usable for some purposes even if the input data may be incomplete, uncertain, or unstable
Areas estimation relates to
Measurement
Time
Distance
Money
Space
Shape
Numerical operations
Rounding off 
A form of estimation; a handy tool to know especially when working with large numbers and provides a clearer mental picture of the number line, in which numbers are presented in a linear manner
Rounding up 
Happens when the value is half or greater than the value being rounded
Rounding down 
Happens when the value is less than half of the number being rounded
Estimation 
Involves making an educated guess using reasoning or comparisons to arrive at a useful approximation
Basic calculation 
Necessary in swine production especially when computing for the total costs and profit
Estimation 
Involves "nearby" or "rounded" numbers that would be easier to work with
Fractions 
Numbers that represent parts of a whole; useful in farm production particularly when dividing something up
Denominator 
The number of parts in a whole
Decimals 
Numbers that describe parts of a whole
Percentages 
Numbers that describe parts of a hundred equal parts represented by "%" sign
Ratio 
A quick way to compare numbers, uses a colon between the numbers; they are especially important to swine raisers
Feed gain rate 
Shows the food consumed by a fattening sow to get one pound of meat
Proportion 
An equation showing two equivalent ratios which can be expressed as two fractions
Units of measurement
Metric
English System
SI (International System of Units)
Based on the metric system & used in Europe
Metric system 
Designed to make calculations and comparisons easier; millimeter, centimeter, meter, and many others
Cylinder 
An object with straight parallel sides & a circular or oval cross-section
Rectangular 
A solid, 3-dimensional object with six rectangular faces
Cube 
A three-dimensional solid object bounded by six square sides
Resistors 
The most essential & frequently used of all the electronic components; main function is to resist current flow, used to set up the correct voltage
Linear resistors 
Those whose (wire) value is directly proportional to the applied voltage
Types of resistors
Fixed
Variable
Nonlinear resistors 
Resistors where the current flowing through them do not change, according to Ohm's Law, but change with the change in temperature or applied voltage
Absolute 
What the value of the resistor color codes is NOT
Tolerance 
The limit on how far the real value of the resistor can deviate from its color coded value
Resistor color coding 
Gives us the color-coded value of a given resistor as well as the maximum and minimum value
Capacitor 
A device that consists essentially of two conducting surfaces separated by a dielectric material like air, paper, mica, ceramic, glass; stores electric energy
Electrical potential or electrostatic field 
Stored electricity; volts electrons will continue
Capacitance 
A property that exists whenever the insulating material permits the storage of electricity
Capacitance units
Farad, Microfarad, and Picofarad
Coil 
Consists of a wire that serves as a conductor where electronic current flows; consists of wire that gives as a conductor where electronic current flows
Conductor 
Made of that is turned around core which arrives to the the nets fold and as the diameter
Semiconductor 
A material that can both conduct and insulate the flow of electric current
Transistor 
A semiconductor component that can amplify, control, generate electric signals
Types of transistors
Bipolar Junction Transistor (BJT)
Field Effect Transistor (FET)
type 
When the material adds up extra electrons, this is what it is called, because it results in more negative charge carriers
type 
When it creates a hole in the crystal structure, this is what it is called, because it results in more positive charge carriers
