What's the purpose of a running total?
- A.
  
  It allows the total to be stated at any point in time without having to substract the entire sequence each time.
- B.
  
  It allows the sequence to be stated at any point in time without having a total
- C.
  
  It allows the total to be stated at any point in time without having to multiply the entire sequence each time
- D.
  
  It allows the total to be stated at any point in time without having to sum the entire sequence each time.
Correct Answer
D. It allows the total to be stated at any point in time without having to sum the entire sequence each time.

Explanation
A running total allows the total to be stated at any point in time without having to sum the entire sequence each time. This means that as new values are added to the sequence, the running total can be easily updated without recalculating the sum from the beginning. This can be useful in various scenarios, such as tracking the cumulative sales of a product or keeping a running tally of scores in a game.

What is the equivalent of a running total when it comes to a subtraction?
- A.
  
  A difference
- B.
  
  A running difference
- C.
  
  A statement
- D.
  
  A rolling difference
Correct Answer
B. A running difference

Explanation
A running difference refers to the ongoing calculation of the difference between two values. It is similar to a running total, but instead of adding values together, it subtracts them. This means that the running difference keeps track of the cumulative difference between values as they are subtracted from each other over time.

What is a finite difference?
- A.
  
  It is a mathematical expression of the form f(x+b)-f(x+a)
- B.
  
  It is a mathematical expression of the form f(x+b)
- C.
  
  It is a mathematical expression of the form f(x+a)
- D.
  
  It is a mathematical expression of the form f(b)-f(a)
Correct Answer
A. It is a mathematical expression of the form f(x+b)-f(x+a)

Explanation
A finite difference is a mathematical expression that calculates the difference between two values of a function, where one value is shifted by a constant amount (b) and the other value is shifted by a different constant amount (a). This expression, f(x+b)-f(x+a), represents the finite difference between the function values at x+b and x+a.

What tool uses running totals all the time?
- A.
  
  Cash registers
- B.
  
  Calculators
- C.
  
  TV
- D.
  
  A watch
Correct Answer
A. Cash registers

Explanation
Cash registers use running totals all the time to keep track of the total sales and calculate the change to be given back to the customer. They continuously update the total amount as each item is scanned or entered, ensuring an accurate and up-to-date running total. This feature is essential for efficient and accurate financial transactions in retail and other businesses.

What's a series in mathematics?
- A.
  
  It is a description of the operation of dividing infinitely many quantities to a given ending quantity
- B.
  
  It is a description of the operation of removing infinitely many quantities to a given starting quantity
- C.
  
  It is a description of the operation of adding infinitely many quantities to a given starting quantity
- D.
  
  It is a description of the operation of substracting infinitely quantities to a given starting quantity
Correct Answer
C. It is a description of the operation of adding infinitely many quantities to a given starting quantity

Explanation
A series in mathematics is a description of the operation of adding infinitely many quantities to a given starting quantity. This means that in a series, numbers are added together in a specific order and the sum of these numbers can approach infinity. The concept of a series is fundamental in calculus and is used to study the behavior of functions and solve various mathematical problems.
