Math Terms StartingWith F

In this page math terms startingwith f we are going to see definitions of mathematical terms starting with the letter "F". We have listed out almost terms in math starting with F.In math also it is very important to know the meaning of many important words which are being used in the subject math.Each term is defined and examples are provided where ever it is necessary. Links are given for every words, by using this students can learn the meaning and its application more clearly.Here are the math terms startingwith f.




Face is a surface bounded by edges of a three dimensional solids.

Face of a polyhedron: Face of a polyhedron is any of the two dimensional polygons, that makes its boundary of a polyhedron. Each face is a polygon.


Factor is a number which divides another number exactly. For example 5 is a factor of 25 and 3 is factor of 27.


Factorial of a number 'n' is a product of consecutive numbers from 1 to n. It is denoted by 'n!'.
For example 4! = 1x2x3x4 = 24. This concept is used in combinations


The method to break down a number into its factors. we can factor a number. To check whether the give number is a perfect square we need to use prime factorization.

Factor tree

A method or graphical representation to find the prime factors of a number.


Fahrenheit is a temperature scale named after the famous scientist Daniel Gabriel Fahrenheit. The freezing point of water is 32°F.

Fibonacci sequence

A sequence of numbers  0,1,1,2,3,5,8,13, which each number is equal to the sum of the previous two numbers. It is occurred by recurrence relation.

Foil method 

In the word FOIL

F represents multiplying the first terms

O represents multiplying out side terms

I represents multiplying inside terms

L represents multiplying last terms.

Finite set

      A set which has finite number of elements is called finite set. In other words, a set whose cardinal number is countable or finite is called as finite set.

Empty set is a finite set, because the cardinal number of empty set is 0.

For example:

  • A={x:x is an even number less than 12}           A={2,4,6,8,10}. Here the cardinal number of A is 5 that is countable, so A is a finite set.
  • B=Days of a week.           n(B)=7, so B is finite.
  • C={20, 30, 40,....100}           here the cardinal number of C is countable, so it is finite set


It consists of two numbers separated by a line. To represent fraction we use horizontal line to separate the upper part (how many parts are taken into consideration) and lower part (the total number of parts). Upper part is called as numerator and lower part is called as denominator. Example ⅜ In this fraction 3 is known as numerator and 8 is known as denominator.


A function is a well behaved relation.

'Well behaved relation' means, for a given a starting point in the starting set(domain), we know exactly where to go in the end set(range).

All functions are relations, but not all relations are functions.

In the above example, students related with heights, the relation is not well behaved, so it is not a function.

Fraction into percent

General rules for changing a fraction as percentage

Step 1:  First we have to multiply the given fraction with 100.

Step 2: Now we have to multiply the numerator with 100.

Step 3: If it is possible we can simplify using tables

Step 4: Now we have to write the simplified number with percentage %.

Frequency Distribution

Frequency distribution is the arrangement of raw data into tabular form. The data can be arranged into classes according to the size along with the corresponding frequencies.

Frequency is how often something occurs

For example Peter played soccer on

  • Sunday morning
  • Sunday evening
  • Wednesday morning
  • Friday evening

Here the frequency is 2 on Sunday and 1 on Wednesday and 1 on Friday. The total number of times is 4 and it is for the whole week.

These are the word in math terms startingwith f.
