Arithmetic Operations on Functions

Sum (f + g)(x) = f(x) + g(x)
Difference (f - g)(x) = f(x) - g(x)
Product (f × g)(x) = f(x) × g(x)
Quotient (f/g)(x) = f(x)/g(x), if g(x) is not equal to 0.

Negative Numbers Addition

Rule Example
  • Positive Number + Positive = Positive Number
     
7 + 4 = 11
2 + 15 = 17
 
  • Negative Number + Negative Number = Negative Number
     
-4 + (-9) = -(4 + 9) = -13
-12 + (-43) = -(12 + 43) = -55

 
  • Positive + Negative OR Negative + Positive

    case 1: The positive number is larger: Answer = Positive

    case 2: The negative number is larger: Answer = Negative

     
case 1:
14 + (-5) = 14 - 5 = 9

case 2:
-19 + 7 = -(19 - 7) = -12

Absolute Value

  | -x | = x
  | xy | = | x | × | y |
| x |2 = x2
| x | = a, then x = -a or x = a
| x | < a, then -a < x < a
| x | > a, then x < -a or x > a


Basic Identities

  • Closure Axiom of Addition
        Sum (or difference) of 2 real numbers equals a real number.
     
  • Additive Identity
        a + 0 = a
        e.g. 5 + 0 = 5 and 0 + 5 = 5
  • Additive Inverse
        a + (-a) = 0
        e.g. 3 + (-3) = 0
  • Associative of Addition
        (a + b) + c = a + (b + c)
        e.g. (2 + 3) + 5 = 2 + (3 + 5)
  • Commutative of Addition
        a + b = b + a
        e.g. 3 + 4 = 4 + 3
  • Definition of Subtraction
        a - b = a + (-b)
        e.g. 4 - 6 = 4 + (-6)
  • Closure Axiom of Multiplication
        Product (or quotient if denominator is not equal to 0) of 2 real numbers equal to a real number.
     
  • Multiplicative Identity
        a × 1 = a
        e.g. 6 × (1) = 6 and 1× (6) = 6
  • Multiplicative Inverse
        a × (1/a) = 1 (a is not equal to 0)
        e.g. 6 × (1/6) = 1
  • Multiplication Times Zero
        a × 0 = 0
        e.g. 7 × 0 = 0
  • Associative of Multiplication
        (a × b) × c = a ×(b × c)
        e.g. (2 × 3) × 6 = 2 × (3 × 6)
  • Commutative of Multiplication
        a × b = b × a
        e.g. 4 × 6 = 6 × 4
  • Distributive Law
        a (b + c) = ab + ac
        e.g. 2 (3 + x) = 2(3) + 2(x)
  • Definition of Division
        a/b = a(1/b)
        e.g. 3/5 = 3(1/5)


Exponents and Powers

X0 = 1, X is not equal to 0.
X1 = X
X(-a) = 1/Xa
XaXb = Xa+b
(XY)a = XaYa
(Xa)b = Xab
Xa/Xb = X(a-b), X is not equal to 0.
(X/Y)a = Xa/Ya, X and Y are not equal to 0.
(X/Y)a = Xa/Ya
X1/b =   ,the bth root of X
Xa/b =   , the bth root of X raised to the a



Logarithm

logb(1) = 0
logbb = 1
logb (x × y) = logb(x) + logb(y)
logb(x/y) = logb(x) - logby
logb(xn) = n logb(x)

Factorials
The factorial of a number is the product of all the whole numbers, except zero, that are less than or equal to that number.

 

1! 1 = 1
2! 2 × 1 = 2
3! 3 × 2 × 1 = 6
4! 4 × 3 × 2 × 1 = 24
5! 5 × 4 × 3 × 2 × 1 = 120
6! 6 × 5 × 4 × 3 × 2 × 1 = 720
7! 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5,040
8! 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 40,320
9! 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 362,880
10! 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 3,628,800
11! 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 39,916,800
12! 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 479,001,600


 

Consecutive Integers

 

Term Example Variable Using
Consecutive Integers 4, 5, 6, 7 x, x+1, x+2, x+3
Consecutive Even Integers 2, 4, 6, 8 x, x+2, x+4, x+6
Consecutive Odd Integers 3, 5, 7, 9 x, x+2, x+4, x+6



Example:
If the sume of the first and third consecutive integers is increased by 8, the result is 5 less than
triple the second integer. Find the integers.

Solution:
Let first integer = x,
second integer = x + 1,
third integer = x +2,
x + (x+2) + 8 = 3(x+1) - 5
