Q
A
24
Q

What makes zero a significant figure?

A
  • between two non zero digits
  • at the end of a number with a decimal place
25
Q

  • at the end of a number without a decimal
26
Q

What equalitites should the answer share with the signifigant figures when multiplying/dividing?

A

The answer must have the same number of significant figures as the original number with the fewest significant figures

27
Q

What equalitites should the answer share with the signifigant figures when adding/subtracting?

A

Drop the number and the proceeding digits

29
Q

Rule for Rounding Numbers if the first digit to be dropped is between 5 and 9

Infinite

31
Q

What is the Scientific Notation Format

A

y x 10^(x)

32
Q

What is the coefficient in scientific notation?

A

The y that represents a number that is greater than or equal to 1, and less than 10

33
Q

What is the exponent in scientific notation?

A

The x that is a positive or negative whole number

34
Q

How to convert from Standard Number to Scientific Notation

A
  1. Move the decimal point to give a number between 1 and 10
  2. Multiply the result by 10^(x), where x = the number of places the decimal was moved
35
Q

Decimal movement rules for converting from standard number to scientific notation

A
  • Decimal moved the left, the exponent is positive
  • Decimal moved to the right, the exponent is negative
36
Q

How to convert from Scientific Notation to Standard Number

A
  1. See if exponent is positive or negative
  2. Move the decimal the amount of spaces that match the exponent
37
Q

Decimal movement rules for converting from scientific notation to standard number

A
  • When the exponent is positive, move the decimal point x places to the right
  • When the exponent is negative, move the decimal point x places to the left
