## Antilog: How to find anti Logarithm of Numbers

Antilog: The words “Anti Logarithm of numbers” simply means the opposite of logarithm of numbers which we have discussed here. It is also provided in the four figure table immediately after the table of logarithm of numbers. The antilog contains number having the corresponding logarithm in the four figure table. When looking for the anti […]

## How to find Percentage 2

Q1: If 12% of x is equal to 6% of y, then 18% of x will be equal to how much percent of y? Solution: 12% of x = 6% of yx(12%) = y(6%) Let 18% of x = a% of yx(18%) = y(a%) x(12%) = y(6%)x(18%) = y(a%) Cross multiply x(12%) X y(a%) =

## Log number: Logarithm of Numbers

Log Number: We are going to look into the use of logarithm of numbers in this very Article. The logarithm of a number (let’s say “N”) to a particular base (let’s say “b”) is that power/index to which “b” MUST be raised to give us “N”. Good knowledge of standard form will help a student

## Exponential Functions

Exponential Functions: In indices, sometimes you will see an unknown being the index/power or even the base of a function, in this situation, it is called an exponential Function. For you to solve such equation, you must express both sides to be in the same index or base as the case may be. Example 1:

## Laws of Indices

Laws of indices: Index Notation is said to be a method of reducing/shortening the product of numbers that have equal factors or numbers that are the same. For instance if we have 4 x 4 x 4 x 4. We can shorten the product of the numbers by taking one of the equal factors “4”

## Rationalization of surds

You can only add or subtract Surds in the same basic form. Sometimes if the surds are not in the same basic form and needed to be simplified and brought to the same basic form before the addition or subtraction will be carried out. Note:√a + √a = 2√a2√b – 3√b = – √b √a

## Operations with Surds

Operations with Surds Whenever they talk about Surds, just bear it in mind they are directly talking about irrational numbers which can not be expressed as fraction. The reason why Surds are irrational numbers is because their exact values can not be determined. The square root of all non perfect squares are irrational, π and

## Reciprocals of Numbers

The Reciprocal of any given number “x” is 1(one) all over that particular given number “x” = 1/x. (Reciprocals of Numbers) When two numerals multiply themselves and the product is 1, the two numerals are said to be reciprocals of each other. If a numeral is represented with the letter N, and N is not

## How to find square roots of numbers without using calculator

Table of square roots are two types, to estimate a square root of a number from the four figure table is more difficult than doing same in the table of Squares. The two types of Tables of SQUARE ROOTS are: 1). Square root of numbers between 1 and 10 2). Square root of numbers between

## How to find Squares of any numerals without using calculator: squares of numbers

The squares of numbers are gotten when the number is multiplied by itself. When T is multiplied by T, that is T x T, it is being written as T² in a short form. Some examples of Squares are: 0.3² = 0.3 x 0.3 = 0.092.5² = 2.5 x 2.5 = 6.257² = 7 x
