What are Roman numerals?
Letters from the Roman alphabet used to represent numbers (e.g., I = 1, V = 5, X = 10).
What are the key Roman numeral values?
A:
I = 1
V = 5
X = 10
L = 50
C = 100
D = 500
M = 1,000
Can a numeral be repeated more than three times?
No, numerals like I, X, and C can be repeated up to three times (e.g., XXX = 30), but no more.
When is a smaller numeral added to a larger numeral?
When a smaller numeral follows a larger numeral (e.g., VI = 6).
When is a smaller numeral subtracted from a larger numeral?

How do you convert Fahrenheit to Celsius?
C = (F - 32) / 1.8
How do you convert Celsius to Fahrenheit?
F=(C×1.8)+32.
Convert 98.6°F to Celsius.
C = (98.6-32) / 1/8 = 37 C
Convert 37°C to Fahrenheit.
F=(37×1.8)+32=98.6°F.
What is an alternate formula for converting between Fahrenheit and Celsius?
9C=5F−160, solve for either Celsius or Fahrenheit.
What are the freezing and boiling points of water in Celsius and Fahrenheit?
Celsius: Freezing 0°C, Boiling 100°C
Fahrenheit: Freezing 32°F, Boiling 212°F
