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

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) |
 |

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

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
