# Online Calculators & Converter For Students

Standard Form Calculator:

Scientific Notation Calculator and Converter This free scientific notation calculator and converter allows you to perform various scientific notation operations, including addition, subtraction, multiplication, and division of numbers.

It can also convert real decimals to scientific notation and vice versa. Scientific notation calculator, just enters the numbers in scientific notation, select the operation and click “Calculate” to generate the result. What is scientific notation?

A scientific term also called “standard form” or “exponential form”, represents a numeric value written in the following form: a × 10n (1 ≤ Very large and very small numbers can be Examples of scientific notation that are easy to characterize: 3,500,000 = 3.5 × 106; 0. 0000425 = 4.25 x 10 -5.

When scientific notation is used, a large number is converted to the corresponding decimal number from 1 to 10, multiplied by 10, increased to the specified positive power, and small numbers are converted to the corresponding decimal number between 1 and 10, multiplied by 10 on the given negative performance.

Converting numbers to numerical forms can be of great benefit in many disciplines such as engineering, math, and computer science.

When E notation is used, the letter e or E replaces the factor “multiplied by 10 to the power” and the number after “e” indicates the number of powers of 10.

LCM Calculator:

The LCM calculator takes two or more numbers and calculates the least common multiple, which is the smallest positive integer that can be divided by each of those numbers.

A more systematic way to find the LCM of some integers is to use prime factorization. Prime factors consist of breaking down each of the numbers being compared into its product of prime numbers. The LCM is then determined by multiplying the greater power of each prime number.

Note that while calculating LCM in this way  is more efficient than using the “brute force” method, it is still limited to smaller numbers. The following example explains how to use prime factors to determine the LCM.

Sig Fig Calculator:

The sig fig calculator online allows you to convert any number or expression to a new number with the desired number of significant digits.

This calculator also works as a sig-fig counter which counts the number of significant digits in a number and also finds which numbers are significant. Just consider this smart calculator to train with significant numbers and get accurate results that match significant numbers
