Value

MATHEMATICAL VALUE:

In mathematics, value is the 'output' of a function. Basically that of unary, single-valued, there is one input )and one output.

Numerical Coefficient

NUMERICAL COEFFICIENT:

A numerical coefficient is a factor that multiplies in some term of an expression, it is usually a number, but it

does not involve any variables of the expression

Math Definitions Again

Variable: A letter that represents an unknown matter.

eg. x,a,n or f

Expression: Any single number or variable or combination of operation (-,+,x,÷) involving numbers and variables.

eg. 5,n,8t,x+1,2y-7

Value: A known or calculated amount.

Constant: A number that does not change and it increases or decreases the value of an expression.

Numerical coefficient: A number that multiplies the variable.

eg. 2t

Pi is the ratio of the circumference of a circle to its diameter. It is known to be irrational and its decimal expansion so it does not terminate or repeat. The first 20 places are:

3.14159 26535 89793 23846

This is some of what we learned in ENRICHED MATH.

Lowest Common Denominator.

In mathematics, the lowest common denominator or least common denominator (abbreviated LCD) is the least common multiple of the denominators of a set of fractions without the same. It is the smallest multiple of the denominators.

Divisibility Rules continued.

8-If the number is divisible by 2 twice,
9-If the sum of the number is divisible by nine.
10-if the number ends in 0.

Divisibility Rules

1- Every whole number are divisible by 1.
2-All even numbers (ending in 0,2,4,6,8).
3-If the sum of the number is divisible by 3.
4-If the number is divisible by 2 twice.
5-If it ends in 0,5.
6-If it is divisible by 2 and 3.
7-You can double the last digit and subtract the sum from the rest of the number, and set an answer that is divisible by 7 ( including 0).

The Divisibility Rule Number Four

A number is divisible by four if it can be divided by two twice.

400 divided by 2=200

200 divided by 2=100

100 is the answer.

An easier way is 400 divided by 4= 100
